وکیپیڈیا:Manual of Style (dates and numbers)

سانچہ:Style-guideline سانچہ:Style

This page guides the presentation of numbers, dates, times, measurements, currencies, coordinates, and similar material in articles. Its aim is to promote clarity and cohesion; this is especially important within an article. The goal is to make the whole encyclopedia easier and more intuitive to use.

Where this manual provides options, consistency should be maintained within an article unless there is a good reason to do otherwise. The Arbitration Committee has ruled that editors should not change an article from one guideline-defined style to another without a substantial reason unrelated to mere choice of style, and that revert-warring over optional styles is unacceptable.[۱] If discussion cannot determine which style to use in an article, defer to the style used by the first major contributor.

General notes[سودھو]

Quotations, titles, etc.[سودھو]

ہور دیکھو: WP:MOSQUOTE

Quotations, titles of books and articles, and similar "imported" text should be faithfully reproduced, even if they employ formats or units inconsistent with these guidelines or with other formats in the same article. If necessary, clarify via [bracketed interpolation], article text, or footnotes.

  • It is acceptable to change other date formats in the same article to provide consistency, so long as those changes would otherwise be acceptable.

Non-breaking spaces[سودھو]

Guidance on the use of non-breaking spaces ("hard spaces") –  ,

{{nbsp}},  ,
{{thinsp}} – is given in some sections below;
{{nowrap}} may also be useful in controlling linebreaks in some situations. Not all situations in which hard spaces or

{{nowrap}} may be appropriate are described. سانچہ:Crossref

WP:EPHEMERAL


Except on pages updated regularly (e.g. current events), terms such as سانچہ:!xt, سانچہ:!xt, سانچہ:!xt, سانچہ:!xt, سانچہ:!xt, and سانچہ:!xt should usually be avoided in favor of phrases such as سانچہ:Xt and سانچہ:Xt. For future and current events, use phrases such as سانچہ:Xt or سانچہ:Xt to signal the time-dependence of the information. Using {{as of|۲۰۲۴}} will produce the text سانچہ:Xt and adds the article to a category flagging it for periodic review. However, do not replace سانچہ:Xt with {{as of|2005}} because some information (the start of 2005) would be lost; advanced features of
{{as of}} such as {{as of|2005|alt=since the start of 2005}} can be used in such circumstances.

Relative-time expressions are acceptable for very long periods, such as geological epochs: سانچہ:Xt

Time of day[سودھو]

Shortcuts:
WP:MOSTIME
MOS:TIME

Context determines whether the 12- or 24-hour clock is used; in both, colons separate hours, minutes and seconds (e.g. سانچہ:Xt or سانچہ:Xt).

{{nbsp}}p.m. or 2:30

{{nbsp}}pm), not سانچہ:!xt or سانچہ:!xt. Hours should not have a leading zero (e.g. سانچہ:Xt, not سانچہ:!xt). Usually, use سانچہ:Xt and سانچہ:Xt rather than سانچہ:!xt and سانچہ:!xt; whether "midnight" refers to the start or the end of a date should be explicitly specified unless clear from the context.

The numerical elements of times-of-day are figures (سانچہ:Xt) rather than words (سانچہ:!xt) though conventional terms such as سانچہ:Xt and سانچہ:Xt are acceptable (taking care, with the latter, to avoid possible date ambiguity in constructions such as سانچہ:Xt).

Time zones[سودھو]

Shortcut:
WP:TIMEZONE
Give dates and times appropriate to the time zone where an event took place. For example, the date of the attack on Pearl Harbor should be December

 7, 1941 (Hawaii time/سانچہ:Zwspdate). Give priority to the place at which the event had its most significant effects; for example, if a hacker based in China attacked a Pentagon computer in the US, use the time zone for the Pentagon, where the attack had its effect. In some cases the best solution may be to add the date and time in Coordinated Universal Time (UTC). For example:

  •   سانچہ:Xt

Alternatively, include just the UTC offset:

  •  سانچہ:Xt

Rarely, the time zone in which a historical event took place has since changed; for example, China to 1949 was divided into five time zones, whereas all of modern China is UTC+8. Similarly, the term "UTC" is not appropriate for dates before this system was adopted in 1960;[۲] Universal Time (UT) is the appropriate term for the mean time at the prime meridian (Greenwich) when it is unnecessary to specify the precise definition of the time scale. Be sure to show the UTC or offset appropriate to the clock time in use at the time of the event, not the modern time zone, if they differ.

Consistency[سودھو]

Shortcut:
MOS:DATEUNIFY
  • Dates in article body text should all use the same format: سانچہ:Xt, but not سانچہ:!xt.
  • Publication dates in an article's citations should all use the same format, which may be:
For example, a single article might contain one, but only one, of:
سانچہ:Xt
سانچہ:Xt
(among other possibilities).
  • Access and archive dates in an article's citations should all use the same format, which may be:
For example, a single article's citations might contain either of the following:
سانچہ:Xt
سانچہ:Xt
When a citation style does not expect differing date formats, it is permissible to normalize publication dates to the article body text date format, and/or access/archive dates to either, with date consistency being preferred.
Strong national ties to a topic[سودھو]
Shortcut:
MOS:DATETIES
  • Articles on topics with strong ties to a particular English-speaking country should generally use the date format most commonly used in that nation. For the United States this is, for example, سانچہ:Xt; for most other nations it is, for example, سانچہ:Xt.
  • Articles related to Canada may use either format with (as always) consistency within each article.
  • In some topic areas the customary format differs from the usual national one: for example, articles on the modern U.S. military use day-before-month, in accordance with U.S. military usage.
Retaining existing format[سودھو]
Shortcut:
MOS:DATERET


  • If an article has evolved using predominantly one format, the whole article should conform to it, unless there are reasons for changing it based on strong national ties to the topic or consensus on the article's talk page.
  • The date format chosen by the first major contributor in the early stages of an article should continue to be used, unless there is reason to change it based on strong national ties to the topic or consensus on the article's talk page.
  • Where an article has shown no clear sign of which format is used, the first person to insert a date is equivalent to "the first major contributor".

Era style[سودھو]

Shortcuts:
WP:ERA
WP:BCE

 BP). BP years are given as سانچہ:Xt or spelled out as سانچہ:Xt (not سانچہ:!xt, سانچہ:!xt, سانچہ:!xt, or similar). Do not convert other notations to or from BP unless you are certain of what you are doing. A safer and simpler alternative may be to use سانچہ:Xt.

  • Other era systems may be appropriate in an article. In such cases, dates should be followed by a conversion to Dionysian (or vice versa) and the first instance should be linked: سانچہ:Xt, or سانچہ:Xt.

Julian and Gregorian calendars[سودھو]

Shortcuts:
WP:OSNS
WP:JG


A date can be given in any appropriate calendar, as long as it is (at the minimum) given in the Julian calendar or the Gregorian calendar or both, as described below. For example, an article on the early history of Islam may give dates in both Islamic and Julian calendars. Where a calendar other than the Julian or Gregorian is used, the article must make this clear.

  • Current events are dated using the Gregorian calendar.
  • Dates of events in countries using the Gregorian calendar at that time are given in the Gregorian calendar. This includes some of the Continent of Europe from 1582, the British Empire from 14
 September 1752, and Russia from 14

 February 1918 سانچہ:Crossref.

  • Dates before 15
 October 1582 (when the Gregorian calendar was first adopted in some places) are normally given in the Julian calendar. The Julian day and month should not be converted to the Gregorian calendar, but the start of the Julian year should be assumed to be 1

 January سانچہ:Crossref.

  • Dates for Roman history before 45

 BC are given in the Roman calendar, which was neither Julian nor Gregorian. When (rarely) the Julian equivalent is certain, it may be included.

  • For dates in early Egyptian and Mesopotamian history, Julian or Gregorian equivalents are often uncertain. Follow the consensus of reliable sources, or indicate their divergence.

The dating method used should follow that used by reliable secondary sources (or if reliable sources disagree, that used most commonly, with an explanatory footnote).

At some places and times, the new year began on a date other than 1
 January. For example, in England and its colonies until 1752, the year began on Annunciation Day, 25
 March; سانچہ:Crossref. In writing about historical events, however, years should be assumed to have begun on 1

 January سانچہ:Crossref; if there is reason to use another start-of-year date, this should be noted.

If there is a need to mention Old or New Style dates in an article (as in the Glorious Revolution), a footnote should be provided on the first usage, stating whether the New Style refers to a start of year adjustment or to the Gregorian calendar (it can mean either).

Ranges[سودھو]

سانچہ:Anchors
Shortcuts:
MOS:DOB
WP:BORN
WP:OTHERDATE
WP:DATERANGE
  • A pure year–year range is written (as is any range) using an en dash (– or

{{ndash}}) not a hyphen or slash; this dash is usually unspaced (that is, with no space on either side); and the range's end year is usually abbreviated to two digits:

  •   سانچہ:Xt;
  سانچہ:Xt (not سانچہ:!xt;

  سانچہ:!xt)

سانچہ:Hanging indent
But both years are given in full in the following cases:

  not سانچہ:!xt

  not سانچہ:!xt

  • starting year before 1000
 AD: سانچہ:Xt (not سانچہ:!xt);
  سانچہ:Xt;
  سانچہ:Xt;
  سانچہ:Xt;
  سانچہ:Xt;
  سانچہ:Xt;

  سانچہ:Xt

Markup: 1011سانچہ:T922سانچہ:TBC
  • spanning from BC/BCE to AD/CE: سانچہ:Xt (note spaced en dash)
سانچہ:Hanging indent
Notes:
  • Periods straddling two different years, including sports seasons, are generally written with the range notation (سانچہ:Xt). The slash notation (سانچہ:Xt) may be used to signify a fiscal year or other special period, if that convention is used in reliable sources.
  • A date range may appear in سانچہ:Xt format if it is a range of sports seasons.[۹] This format is also indicated for date ranges appearing in reference citations if any dates (of publication, access, archival) are in سانچہ:Var-سانچہ:Var-سانچہ:Var format, because the range in question could thus be easily mistaken for a سانچہ:Var-سانچہ:Var date: سانچہ:Xt but not سانچہ:!xt Another case is in tables (and lists the items of which begin with date ranges) in which some but not all date ranges span a century (sortability of a date column in a table also requires a consistent format for all entries: 2005–07 will unintentionally sort before 2005–2006).
  • Other "pure" ranges use an unspaced en dash as well:
  سانچہ:Xt;

  سانچہ:Xt

  سانچہ:Xt;

  (but سانچہ:Xt uses a spaced en dash; سانچہ:Crossref)

  • If at least one of the items on either side of the en dash is in a mixed format (containing two or more of day, month, year); carries a modifier such as ت.; or otherwise contains a space; then a spaced en dash (

{{snd}}) is used:

  سانچہ:Xt

  • between dates in different years:
سانچہ:Xt
سانچہ:Hanging indent
سانچہ:Xt

  سانچہ:Xt

سانچہ:Hanging indent
Or use an en dash: (unspaced) سانچہ:Xt;

  (spaced) سانچہ:Xt.

  سانچہ:Xt (not سانچہ:!xt)

  • The

{{Age}} template can keep ages current in infoboxes and so on:

  •  {{age|1989|7|23}} returns: سانچہ:Xt
  •  {{age|1989|7|23}}-year-old returns: سانچہ:Xt
  •  {{age|1989|7|23}} years old returns: سانچہ:Xt

Uncertain, incomplete, or approximate dates[سودھو]

Shortcut:
WP:APPROXDATE
  • To indicate "around", "approximately", or "about", the use of the spaced, unitalicised form سانچہ:Xt (or the

{{circa}} template) is preferred over سانچہ:!xt, سانچہ:!xt, سانچہ:!xt, سانچہ:!xt, or سانچہ:!xt:

  •   سانچہ:Xt
  •   سانچہ:Xt
  •   سانچہ:Xt
  • Where both endpoints of a range are approximate, c. should appear before each date:
  •   سانچہ:Xt (not سانچہ:!xt)
  •   سانچہ:Xt (not سانچہ:!xt)
  • Where birth/death dates have been extrapolated from known dates of activity:
  •   سانچہ:Xt
  •   سانچہ:Xt
  •   سانچہ:Xt
  • When a person is known to have been active ("flourishing") during certain years, سانچہ:Xt, [[Floruit|fl.]], or

{{fl.}} may be used:

  •   سانچہ:Xt
The linked forms should not be used on disambiguation pages, and "active" followed by the range is a better alternative for artists, soldiers and other persons with an occupation.
  • When a date is known to be either of two years (e.g. from a regnal or AH year conversion, or a known age at death):
  •   سانچہ:Xt
  • Other forms of uncertainty should be expressed in words, either in article text or in a footnote: سانچہ:Xt. Do not use a question mark (سانچہ:!xt) for such purposes, as this fails to communicate the nature of the uncertainty.

  • Treat the 1st century AD as years 1–100, the 17th century as 1601–1700, and the second millennium as 1001–2000; similarly, the 1st century BC/BCE was 100–1 BC/BCE, the 17th century was 1700–1601 BC/BCE, and the second millennium 2000–1001 BC/BCE.
    • The 18th century (1701–1800) and the 1700s (1700–1799) are not the same period.
    • When using forms such as سانچہ:Xt ensure there is no ambiguity as to whether e.g. 1700–1709 or 1700–1799, is meant.
    • Note that the sequence of years runs سانچہ:Xt – there is no "year 0".
  • Centuries and millennia are identified using either figures (سانچہ:Xt, not سانچہ:!xt) or words (سانچہ:Xt). When used adjectivally they contain a hyphen (سانچہ:Xt or سانچہ:Xt). Do not capitalize (سانچہ:!xt;

Generally, in article text:

  • "billion" and "trillion" are understood to represent their short-scale values of 109
 (1,000,000,000) and 1012

 (1,000,000,000,000), respectively. Keep this in mind when translating articles from non-English Wikipedias, or using material from non-English sources.

  • سانچہ:Xt (unspaced) or سانچہ:Xt (unspaced) respectively may be used for "million" or "billion" after a number, when the word has been spelled out at the first occurrence (e.g., سانچہ:Xt).
  • SI prefixes and symbols, such as سانچہ:Xtn (سانچہ:Xtn) and سانچہ:Xtn (سانچہ:Xtn), should be restricted to use in scientific and engineering expressions.
  • Sometimes, the variety of English used in an article may necessitate the use of a numbering system other than the Western thousands-based system. For example, the South Asian numbering system is conventionally used in South Asian English. In those situations, link the first spelled-out instance of each quantity (e.g. [[crore]], which yields crore). (If no instances are spelled out, provide a note after the first instance directing the reader to the article about the numbering system.) Also, provide a conversion to Western numbers for the first instance of each quantity, and provide conversions for subsequent instances if they do not overwhelm the content of the article. For example, write سانچہ:Xt. Group digits in Western thousands-based style (e.g., سانچہ:Xt; not سانچہ:!xt); سانچہ:Crossref. (Note that the variety of English does not uniquely determine the method of numbering in an article. Other considerations, such as conventions used in mathematics, science and engineering, may also apply, and the choice and order of formats and conversions is a matter of editorial discretion and consensus.)
Shortcut:
WP:NUMNOTES

Notes and exceptions:

  • In tables and infoboxes, quantities are expressed in figures (سانچہ:Xt); but numbers within a table's explanatory text and comments follow the general rule.
  • Numbers in mathematical formulae are never spelled out (سانچہ:Xt, not سانچہ:!xt).
  • Comparable quantities should be all spelled out or all in figures:
  •  سانچہ:Xt, not سانچہ:!xt.
  •  سانچہ:Xt, not سانچہ:!xt
  •  سانچہ:Xt (even though "3" would normally be given as "three") or سانچہ:Xt (or "two hundred and six" for British English, even though "two hundred six" would normally be given as "206"), not سانچہ:!xt.
  • Personal ages are typically stated in figures (سانچہ:Xt) except for large, approximate values (سانچہ:Xt).
  • Sometimes figures and words carry different meanings; for example سانچہ:Xt implies there is a single exception (we don't know which), while سانچہ:Xt means that only locker number 1 was not searched.
  • Proper names, technical terms, and the like are never altered: سانچہ:Xt;
  سانچہ:Xt;
  سانچہ:Xt;
  سانچہ:Xt;
  سانچہ:Xt;
  سانچہ:Xt;
  سانچہ:Xt;

  • Avoid beginning a sentence with figures:
  •   Not سانچہ:!xt, but سانچہ:Xt or سانچہ:Xt.
  •   Not سانچہ:!xt (nor سانچہ:!xt – because comparable numbers should be both written in words or both in figures) but سانچہ:Xt
  • Exception: Where a proper name, technical term, etc., itself beginning with a numeral, opens the sentence (سانچہ:Xt) although this can usually be avoided by rewording (سانچہ:Xt).

MOS:DIGITS
  • Digits should be grouped and separated either by commas or narrow gaps (never a period/full point).
Grouping with commas
  • Left of the decimal point, five or more digits are grouped into threes separated by commas (e.g.  سانچہ:Xt,  سانچہ:Xt,  سانچہ:Xt,  سانچہ:Xt).
  • Numbers with exactly four digits left of the decimal point may optionally be grouped (either  سانچہ:Xt  or  سانچہ:Xt), provided that this is consistent within each article.
  • When commas are used left of the decimal point, digits right of the decimal point are not grouped (i.e. should be given as an unbroken string).
  • Markup: {{formatnum:}} produces this formatting.
Grouping with narrow gaps
  • Digits are grouped both sides of the decimal point (e.g.  سانچہ:Xt,  سانچہ:Xt,  سانچہ:Xt).
  • Digits are generally grouped into threes. Right of the decimal point, usual practice is to have a final group of four instead of a lone digit (e.g.  سانچہ:Xt  or  سانچہ:Xt). In mathematics-oriented articles long strings may be grouped into fives (e.g.  سانچہ:Xt).
  • This style is especially recommended for articles related to science, technology, engineering or mathematics.
  • Markup: Templates
{{val}} or

{{gaps}} may be used to produce this formatting. Note that use of any space character in numbers, including non-breaking space, is problematic for screen readers. سانچہ:Crossref Screen readers read out each group of digits as separate numbers (e.g.  30&thinsp;000  is read as "thirty zero zero zero".)

  • Delimiting style should be consistent throughout a given article.
  • Either use commas or narrow gaps, but not both in the same article.
  • Either group the thousands in a four-digit number or do not, but not mixed use in the same article.
  • However, grouping by threes and fives may coexist.

  • Where explicit uncertainty information (such as a margin of error) is available and appropriate for inclusion, it may be written in various ways:
  •  سانچہ:Xt
  •  سانچہ:Xt (not used with scientific notation)
  •  سانچہ:Xt
  •  سانچہ:Xt (equivalent to سانچہ:Xt)[۱۰]
  •  سانچہ:Xt
Markup:
{{+-}},
{{su}}, and

{{val}} may be used to format uncertainties.

  • Where explicit uncertainty is unavailable (or is unimportant for the article's purposes) round to an appropriate number of significant digits; the precision presented should usually be conservative. Precise values (often given in sources for formal or matter-of-record reasons) should be used only where stable and appropriate to the context, or significant in themselves for some special reason.
  •   سانچہ:Xt
but سانچہ:Xt
  •   سانچہ:Xt (not سانچہ:!xt – an official figure unlikely to be accurate at full precision)
but سانچہ:Xt (unusual case in which the full-precision official population figure is helpful to readers)
  •   سانچہ:Xt (likely that accurate and precise figures were determined)
  •   سانچہ:Xt (unlikely that any precise number can be accurate, even if an official figure is issued)
or سانچہ:Xt (in reporting conflicting information, give detail sufficient to make the contrast intelligible)
  •   سانچہ:Xt (where the actual figure was $8,462,247.63) سانچہ:Xt
  • The number of decimal places should be consistent within a list or context (سانچہ:Xt, not سانچہ:!xt), unless different precisions are actually intended.
  • It may sometimes be appropriate to note the lack of uncertainty information, especially where such information is normally provided and necessary for full interpretation of the figures supplied.
  •   سانچہ:Xt
  • The

{{undue precision}} template may be added to figures appearing to be overprecise.

  • Avoid using "approximately", "about", and similar terms with figures that have merely been approximated or rounded in a normal and expected way, unless the reader might otherwise be misled.
  •   سانچہ:Xt (not سانچہ:!xt – heights are conventionally reported only to the nearest inch, even though greater precision may be available in principle)
but سانچہ:Xt ("about" because here the precise value is unknown, with substantial uncertainty)
  • The reader may be assumed to interpret large round numbers (سانچہ:Xt) as approximations. Writing a quantity in words (سانچہ:Xt) can further emphasize its approximate nature.

  • In non-scientific articles relating to the United States, the primary units are US customary, e.g. سانچہ:Xt.
  • In non-scientific articles relating to the United Kingdom, the primary units for most quantities are metric or other internationally used units,[۱۱] except that:
    • UK engineering-related articles, including those on bridges and tunnels, generally use the system of units that the topic was drawn up in (but road distances are given in imperial units, with a metric conversion – see next bullet);
    • the primary units for distance/سانچہ:Zwsplength, speed and fuel consumption are miles, miles per hour, and miles per imperial gallon (except for short distances or lengths, where miles are too large for practical use);
    • the primary units for personal height and weight are feetسانچہ:Zwsp/inches and stones/سانچہ:Zwsppounds;
    • imperial pints are used for quantities of draught beer/سانچہ:Zwspcider and bottled milk;
  • In all other articles, the primary units chosen will be SI units, non-SI units officially accepted for use with the SI, or such other units as are conventional in reliable-source discussions of the article topic (such as revolutions per minute (rpm) for angular speed, hands for heights of horses, et cetera).

Special considerations:

  • Quantities set via definition (as opposed to measured quantities) should be given first in the units used in the definition, even if this makes the structure of presentation inconsistent: سانچہ:Xt.
    • This may benefit from a slightly non-standard structure, such as سانچہ:Xt. In this sort of case, using سانچہ:Xtn can help make clear which is the statutory, exact value.
  • Nominal quantities (e.g. سانچہ:Xt) require consideration of whether the article is concerned with the item's actual dimensions or merely with its function. In some cases only the nominal quantity may suffice; in others it may be necessary to give the nominal size (often in non-SI units), the actual size in non-SI units, and the actual size in SI units.
  • Whenever a conversion is used, ensure that the precision of the converted quantity in the article is comparable to the precision of the value given by the source سانچہ:Crossref.
  • Where the article's primary units differ from the units given in the source, the

{{convert}} template's |order=flip flag can be used; this causes the original unit to be shown as secondary in the article, and the converted unit to be shown as primary: {{convert|200|mi|km|order=flip}}سانچہ:Xt

Unit names and symbols[سودھو]

Definitions:
  • Examples of unit names: foot, meter, kilometer.
  • Examples of unit symbols: ft, m, km.
  • Unit names and symbols should follow the practice of reliable sources.
  • In prose, unit names should be given in full if used only a few times, but symbols may be used when a unit (especially one with a long name) is used repeatedly, after spelling out the first use (e.g. سانچہ:Xt).
  • Where space is limited, such as in tables, infoboxes, parenthetical notes, and mathematical formulas, unit symbols are preferred.
  • Units unfamiliar to general readers should be presented as a name–symbol pair on first use, linking the unit name (سانچہ:Xt).
  • Ranges use unspaced en dash (
{{ndash}}) if only one unit symbol is used at the end (e.g. سانچہ:Xt), and spaced en dash (

{{snd}}) if two symbols are used (e.g. سانچہ:Xt); ranges in prose may be specified using either unit symbol or unit names, and units may be stated either after both numerical values or after the last (e.g. سانچہ:Xt, سانچہ:Xt, سانچہ:Xt and سانچہ:Xt are all acceptable).

  • Length–width, length–width–height and similar dimensions may be separated by the multiplication sign (×) or the word سانچہ:Xtn.
    • With the multiplication sign, each number should be followed by a unit name or symbol (if appropriate):
  •  سانچہ:Xt, not سانچہ:!xt , سانچہ:!xt nor سانچہ:!xt
  •  سانچہ:Xt
  •  سانچہ:Xt

Quantities of bytes and bits [سودھو]

Shortcut:
WP:COMPUNITS

In quantities of bits and bytes, the prefixes سانچہ:Xtn (symbol سانچہ:Xtn or سانچہ:Xtn), سانچہ:Xtn (سانچہ:Xtn), سانچہ:Xtn (سانچہ:Xtn), سانچہ:Xtn (سانچہ:Xtn), etc., are ambiguous. They may be based on a decimal system (like the standard SI prefixes), meaning 103, 106, 109, 1012, etc., or they may be based on a binary system, meaning 210, 220, 230, 240, etc. The binary meanings are more commonly used in relation to solid-state memory (such as RAM), while the decimal meanings are more common for data transmission rates, disk storage and in theoretical calculations in modern academic textbooks. سانچہ:Bit and byte prefixes Follow these recommendations when using these prefixes in Wikipedia articles:

  • Following the SI standard, a lower-case سانچہ:Xt should be used for "kilo-" whenever it means 1000 in computing contexts, whereas a capital سانچہ:Xt should be used instead to indicate the binary prefix for 1024 according to JEDEC. (If, under the exceptions detailed further below, the article otherwise uses IEC prefixes for binary units, use سانچہ:Xt instead).
  • Do not assume that the binary or decimal meaning of prefixes will be obvious to everyone. Explicitly specify the meaning of k and K as well as the primary meaning of M, G, T, etc. in an article (

{{BDprefix}} is a convenient helper). Consistency within each article is desirable, but the need for consistency may be balanced with other considerations.

  • The definition most relevant to the article should be chosen as primary for that article, e.g. specify a binary definition in an article on RAM, decimal definition in an article on hard drives, bit rates, and a binary definition for Windows file sizes, despite files usually being stored on hard drives.
  • Where consistency is not possible, specify wherever there is a deviation from the primary definition.
  • Disambiguation should be shown in bytes or bits, with clear indication of whether in binary or decimal base. There is no preference in the way to indicate the number of bytes and bits, but the notation style should be consistent within an article. Acceptable examples include:
  •  سانچہ:Xt
  •  سانچہ:Xt
  •  سانچہ:Xt

The IEC prefixes سانچہ:Xtn (symbol سانچہ:Xtn), سانچہ:Xtn (سانچہ:Xtn), سانچہ:Xtn (سانچہ:Xtn), etc., are generally not to be used except:[۱۵]

  • when the majority of cited sources on the article topic use IEC prefixes;
  • in a direct quote using the IEC prefixes;
  • when explicitly discussing the IEC prefixes; or
  • in articles in which both types of prefix are used with neither clearly primary, or in which converting all quantities to one or the other type would be misleading or lose necessary precision, or declaring the actual meaning of a unit on each use would be impractical.

Unit conversions[سودھو]

Shortcuts:
MOS:CONVERSIONS
WP:MOSCONVERSIONS

Where English-speaking countries use different units for the same quantity, follow the "primary" quantity with a conversion in parentheses: سانچہ:Xt; سانچہ:Xt. In science-related articles, however, supplying such conversion is not required unless there is some special reason to do so.

  • Where an imperial unit is not part of the US customary system, or vice-versa – and in particular, where those systems give a single term different definitions – a double conversion may be appropriate: سانچہ:Xt (markup: {{convert|80|kg|lb stlb}}); سانچہ:Xt (markup: {{convert|5|L/100km|mpgus mpgimp|abbr=on}}).
  • Generally, conversions to and from metric units and US or imperial units should be provided, except:
    • When inserting a conversion would make a common or linked expression awkward (سانچہ:Xt).
    • When units are part of the subject of a topic – nautical miles in articles about the history of nautical law (سانچہ:Xt), SI units in scientific articles (سانچہ:Xt), yards in articles about American football – it can be excessive to provide conversions every time a unit occurs. It might be best to note that this topic will use the units (possibly giving the conversion factor to another familiar unit in a parenthetical note or a footnote), and link the first occurrence of each unit but not give a conversion every time it occurs.
  • Converted quantity values should use a level of precision similar to that of the source quantity value, so سانچہ:Xt, not سانچہ:!xt. Small numbers may need to be converted to a range where rounding would cause a significant distortion, so سانچہ:Xt, not سانچہ:!xt. Be careful especially when your source has already converted from the units you're now converting back to. This may be evidenced by multiples of common conversion factors in the data, such as 160 km (from 100 miles). سانچہ:Crossref
  • Conversion templates can be used to convert and format many common units, including

{{convert}}, which includes non-breaking spaces.

  • In a direct quotation, always retain the source units. Any conversions can be supplied either in the quote itself (in square brackets, following the original measurement) or in a footnote. سانچہ:Crossref

Currency names[سودھو]

Currency symbols[سودھو]

  • In general, the first mention of a particular currency should use its full, unambiguous signifier (e.g. سانچہ:Xt), with subsequent references using just the appropriate symbol (e.g. سانچہ:Xt), unless this would be unclear. Exceptions:
  • In an article referring to multiple currencies represented by the same symbol (e.g. the dollars of the US, Canada, Australia, New Zealand, and other countries – سانچہ:Crossref) use the full signifier (e.g. سانچہ:Xt, سانچہ:Xt) each time, except (possibly) where a particular context makes this both unnecessary and undesirable.
  • In articles entirely on EU-, UK- and/or US-related topics, all occurrences may be shortened (سانچہ:Xt, سانچہ:Xt or سانچہ:Xt), unless this would be unclear.
  • The pound sterling is represented by the سانچہ:Xt symbol, with one horizontal bar. The double-barred سانچہ:!xt symbol is ambiguous, as it has also been used for the Italian lira and other currencies. For non-British currencies that use pounds or a pound symbol (e.g. the Irish pound, IR£) use the symbol conventionally preferred for that currency.
  • If there is no common English abbreviation or symbol, follow the ISO 4217 standard. سانچہ:Crossref

Formatting[سودھو]

 

  سانچہ:Xt); but spaced if alphabetic (سانچہ:Xt).

  • Exceptions may occur in tables and infoboxes where space is limited e.g. سانچہ:Xt. It may be appropriate to wikilink such uses, or add an explanatory note.

Conversions[سودھو]

  • Conversions of less-familiar currencies may be provided in terms of more familiar currencies – such as the US dollar, euro or pound sterling – using an appropriate rate (which is often not the current exchange rate). Conversions should be in parentheses after the original currency, rounding to avoid false precision (two significant digits is usually sufficient, as most exchange rates fluctuate significantly), with at least the year given as a rough point of conversion rate reference; e.g. سانچہ:Xt, not سانچہ:!xt.
  • For obsolete currencies, provide an equivalent (formatted as a conversion) if possible, in the modern replacement currency (e.g. decimal pounds for historical pre-decimal pounds-and-shillings), or a US-dollar equivalent where there is no modern equivalent.
  • In some cases it may be appropriate to provide a conversion accounting for inflation or deflation over time. سانچہ:Crossref

Geographical coordinates on Earth should be entered using a template to standardise the format and to provide a link to maps of the coordinates. As long as the templates are adhered to, a robot performs the functions automatically.

First, obtain the coordinates. Avoid excessive precision.

Two types of template are available:

{{coord}} offers users a choice of display format through user styles, emits a Geo microformat, and is recognised (in the title position) by the "nearby" feature of Wikipedia's mobile apps and by external service providers such as Google Maps and Google Earth, and Yahoo.

  • Infoboxes such as
{{Infobox settlement}}, which automatically emit

{{Coord}}.

The following formats are available.

where:

For example:

For the city of Oslo, located at 59° 55′ N, 10° 44′ E:

{{coord|59|55|N|10|44|E}} – which becomes 59°55′N 10°44′E / 59.917°N 10.733°E / 59.917; 10.733

For a country, like Botswana, less precision is appropriate:

{{coord|22|S|24|E}} – which becomes 22°S 24°E / 22°S 24°E / -22; 24

Higher levels of precision are obtained by using seconds:

{{coord|33|56|24|N|118|24|00|W}} – which becomes 33°56′24″N 118°24′00″W / 33.94000°N 118.40000°W / 33.94000; -118.40000

Coordinates can be entered as decimal values

{{coord|33.94|S|118.40|W}} – which becomes 33°56′S 118°24′W / 33.94°S 118.40°W / -33.94; -118.40

Increasing or decreasing the number of decimal places controls the precision. Trailing zeros should be used as needed to ensure that both values have the same level of precision.

London Heathrow Airport, Amsterdam, Jan Mayen and Mount Baker are examples of articles that contain geographical coordinates.

Generally, the larger the object being mapped, the 'less precise the coordinates should be. For example, if just giving the location of a city, precision greater than 100
 meters is not needed unless specifying a particular point in the city, for example the central administrative building. Specific buildings or other objects of similar size would justify precisions down to 10
 meters or even one meter in some cases (1′′ ~15
 m to 30
 m, 0.0001° ~5.6
 m to 10

 m).

The final field, following the E/W, is available for attributes such as type:, region:, or scale: سانچہ:Crossref.

When adding coordinates, please remove the

{{coord missing}} tag from the article, if present.

سانچہ:Crossref

Templates other than

{{coord}} should use the following variable names for coordinates: سانچہ:Var, سانچہ:Var, سانچہ:Var, سانچہ:Var, سانچہ:Var, سانچہ:Var, سانچہ:Var, سانچہ:Var.

  15. Wikipedia follows common practice regarding bytes and other data traditionally quantified using binary prefixes (e.g. سانچہ:Xtn and سانچہ:Xtn, meaning 220 and 210 respectively) and their unit symbols (e.g. سانچہ:Xtn and سانچہ:Xtn) for RAM and decimal prefixes for most other uses. Despite the IEC's 1998 international standard creating several new binary prefixes (e.g. mebi-, kibi-) to distinguish the meaning of the decimal SI prefixes (e.g. سانچہ:Xtn and سانچہ:Xtn, meaning 106 and 103 respectively) from the binary ones, and the subsequent incorporation of these IEC prefixes into the ISO/IEC 80000, consensus on Wikipedia in computing-related contexts currently favours the retention of the more familiar but ambiguous units سانچہ:Xtn, سانچہ:Xtn, سانچہ:Xtn, سانچہ:Xtn, سانچہ:Xtn, سانچہ:Xtn, etc. over use of unambiguous IEC binary prefixes. سانچہ:Crossref
