Template {{convert}} calculates from one measurement unit to another one, and then presents the results, formatted. The complete list of unit symbols recognized by the template is here.
For example:
{{convert|2|km|mi}}
→ Template loop detected: Template:Convert (km entered, converted into miles){{convert|7|mi|km}}
→ Template loop detected: Template:Convert (mi entered, converted into km)Numbers can be rounded, units can be abbreviated into symbols:
{{convert|2|km|mi|2|abbr=on}}
→ Template loop detected: Template:Convert{{convert|7|mi|km|2|abbr=on}}
→ Template loop detected: Template:ConvertValue ranges can be entered using |to|...
or |-|...
:
{{convert|2|to|5|km|mi}}
→ Template loop detected: Template:Convert{{convert|2|-|5|km|mi}}
→ Template loop detected: Template:ConvertCombined effect example:
{{convert|2|-|5|km|mi|2|abbr=on}}
→ Template loop detected: Template:Convert{{convert|2|and|5|km|mi|sigfig=3|abbr=off}}
→ Template loop detected: Template:ConvertEnter units to convert from into:
{{convert|1|lb|kg}}
→ Template loop detected: Template:ConvertBy default, the first quantity shows the unit name, the second shows the symbol (or abbreviation):
{{convert|1|lb|kg}}
→ Template loop detected: Template:ConvertUsing |abbr=in
is the reverse behaviour to the default:
{{convert|1|lb|kg|abbr=in}}
→ Template loop detected: Template:ConvertTo abbreviate both or neither:
{{convert|1|lb|kg|abbr=on}}
→ Template loop detected: Template:Convert{{convert|1|lb|kg|abbr=off}}
→ Template loop detected: Template:Convert|abbr=on
by defaultTemplate {{cvt}} is the same as {{convert}}, except that it has |abbr=on
as the default behaviour. In {{cvt}}, all other options are available. So:
{{cvt|1|lb|kg}}
→ 1 lb (0.45 kg)is equivalent to:
{{convert|1|lb|kg|abbr=on}}
→ 1 lb (0.45 kg)Use |adj=on
to produce the adjectival (hyphenated) form:
A {{convert|10|mi|km|adj=on}} distance
→ A Template loop detected: Template:Convert distance.Default behaviour, for comparison:
{{convert|10|mi|km}} to go
→ Template loop detected: Template:Convert to go.|adj=on
does not produce hyphens with unit symbols, as per :
A {{convert|9|in|cm|adj=on|abbr=on}} nail
→ A Template loop detected: Template:Convert nail.By definition, 100 ft equals Template loop detected: Template:Convert. In practical use, it is common to round the calculated metric number. With that, there are several possibilities.
By {{Convert}} default, the conversion result will be rounded either to precision comparable to that of the input value (the number of digits after the decimal point—or the negative of the number of non-significant zeroes before the point—is increased by one if the conversion is a multiplication by a number between 0.02 and 0.2, remains the same if the factor is between 0.2 and 2, is decreased by 1 if it is between 2 and 20, and so on) or to two significant digits, whichever is more precise. An exception to this is rounding temperatures (see below).

{{convert|123|ft|m|-1}} |
Template loop detected: Template:Convert | |
{{convert|123|ft|m}} |
Template loop detected: Template:Convert | same output as with 0 (below) |
{{convert|123|ft|m|0}} |
Template loop detected: Template:Convert | |
{{convert|123|ft|m|1}} |

{{convert|500|ft|m|-1}} |
Template loop detected: Template:Convert | |
{{convert|500|ft|m}} |
Template loop detected: Template:Convert | same output as with −1 (above), because the conversion factor is between 0.2 and 2 (hence, it should produce same double-zero precision (−2) as in the input value), but the conversion must produce two significant digits at a minimum (hence, a higher single-zero precision (−1) is used) |
{{convert|500|ft|m|0}} |
Template loop detected: Template:Convert | |
{{convert|500|ft|m|1}} |
Template loop detected: Template:Convert | |
{{convert|500|ft|m|2}} |

{{convert|500|ft|cm|-3}} |
Template loop detected: Template:Convert | |
{{convert|500|ft|cm}} |
Template loop detected: Template:Convert | same output as with −3 (above), because the conversion factor is between 20 and 200 (hence, it should decrease input value's double-zero precision (−2) by 2), but the conversion must produce two significant digits at a minimum (hence, a higher triple-zero precision (−3) is used) |
{{convert|500|ft|cm|0}} |

Convert supports four types of rounding:
Specify the desired precision with the fourth unnamed parameter (or third unnamed parameter if the "convert to" parameter is omitted; or fifth unnamed parameter if a range is specified; or fourth unnamed parameter again if a range is specified and the "convert to" parameter is omitted; needs to be replaced with a "precision" named parameter). The conversion is rounded off to the nearest multiple of to the power of this number. For instance, if the result is 8621 and the round number is "-2", the result will be 8600. If the result is "234.0283043" and the round number is "0", the result will be 234.
|sigfig=
To specify the output number to be with n significant figures use |sigfig=<number>
:
{{convert|1200|ft|m|sigfig=4}}
→ Template loop detected: Template:Convert{{convert|1200|ft|m|sigfig=3}}
→ Template loop detected: Template:Convert{{convert|1200|ft|m|sigfig=2}}
→ Template loop detected: Template:Convert{{convert|1200|ft|m|sigfig=1}}
→ Template loop detected: Template:ConvertDefault behaviour, for comparison:
{{convert|1200|ft|m}}
→ Template loop detected: Template:ConvertSetting |sigfig=
to a value less than 1 is meaningless:
{{convert|1200|ft|m|sigfig=0}}
→ Template loop detected: Template:Convert Using |round=5
rounds the outcome to a multiple of 5.
{{convert|10|m|ft}}
→ Template loop detected: Template:Convert{{convert|10|m|ft|round=5}}
→ Template loop detected: Template:ConvertSimilar: using |round=25
rounds the outcome to a multiple of 25.
{{convert|10|m|ft}}
→ Template loop detected: Template:Convert{{convert|10|m|ft|round=25}}
→ Template loop detected: Template:ConvertDefault behaviour, for comparison:
{{convert|10|m|ft|sigfig=4}}
→ Template loop detected: Template:ConvertIn a range, one can round each value individually to the default. Use |round=each
:
{{convert|10 x 200 x 3000|m|ft}}
→ Template loop detected: Template:Convert{{convert|10 x 200 x 3000|m|ft|round=each}}
→ Template loop detected: Template:ConvertSpecify the desired denominator using |frac=<some positive integer>
. (Denominator is the below-the-slash number, for example the 3 in ).
{{convert|5.56|cm|in|frac=16}}
→ Template loop detected: Template:Convert{{convert|8|cm|in|frac=4}}
→ Template loop detected: Template:ConvertThe fraction is reduced when possible:
{{convert|8|cm|in|frac=100}}
→ Template loop detected: Template:ConvertDefault behaviour uses decimal notation:
{{convert|5.56|cm|in}}
→ Template loop detected: Template:ConvertIn temperatures, the conversion will be rounded either to the precision comparable to that of the input value or to that which would give three significant figures when expressed in kelvins, whichever is more precise.
{{convert|10,000|C|F K}}
→ Template loop detected: Template:Convert{{convert|10,000.1|C|F K}}
→ Template loop detected: Template:Convert{{convert|-272|C|F K}}
→ Template loop detected: Template:Convert{{convert|-272|C}}
→ Template loop detected: Template:Convert{{convert|100|C|F K}}
→ Template loop detected: Template:Convert{{convert|0|C|F K}}
→ Template loop detected: Template:ConvertThe precision of the input number in example (1) is one digit, but the precision of its Kelvins expression is three, so the precision of the Fahrenheit conversion is made three (made 180...) . (1) and (2) seem to belie the fact that a Template loop detected: Template:Convert, and make the 32 degrees difference shown in (1) begin to seem off somehow.
Result (1) seems off until you set the significant figures yourself with |sigfig=
:
{{convert|10000|C|sigfig=5}}
→ Template loop detected: Template:Convertor you set the precision positionally, relative to the decimal point (zero being at the decimal point):
{{convert|10000|C|0}}
→ Template loop detected: Template:ConvertThe precision of the input number in example (2) is six, so the precision of the Fahrenheit output is, whereas before, Kelvins had determined it to be three. Examples (3) and (4) show how this can be hidden and generate questions, but it occurs there because the Kelvins conversion generated two fractional parts. (Before it was the input number that generated the fractional part.) In example (3) the three input digits converted into five significant output digits because of the two digits after the decimal point, generated by the Kelvins conversion. This happened again in (5), but in (6) decimal fractions were neither given as input nor induced by the Kelvins conversion.
There is limited support for rounding the displayed input number. The rounding takes place after conversion, so the output is based on the full-precision input. This is useful when the input is produced by Template:Tlc or otherwise available to a higher precision than is usefully displayed, and it's desirable to avoid double-rounding.
To round the input to a specified number of digits after the decimal point, use one of the parameters:
|adj=ri0
|adj=ri1
|adj=ri2
|adj=ri3
Note that there is no |adj=ri-1
or similar for rounding above the decimal place. Neither is there support for significant figures, multiples of 5, or any other output-rounding feature.
The default precision is computed based on the input, so an explicit output precision must usually be supplied:
In this case, if the input were rounded before conversion, a different result would be obtained:
Separate the multiple output units by a space:
{{convert|10|C|F K}}
→ Template loop detected: Template:Convert{{convert|5|km|mi nmi}}
→ Template loop detected: Template:ConvertIf the output unit names contain spaces, use +
as the separator.

A range converts two values and separates them by your choice of words and punctuation.
Range indicators are entered as the second parameter (between the values). Range separators can be:

→ Template loop detected: Template:ConvertUse ×
, multiplication sign, or x
, letter:
{{convert|6|x|12|m|ft}}
→ Template loop detected: Template:ConvertIn science, the formal way is to set |x|
and |abbr=on
(keeping dimensions right, like in area = x km2):
{{convert|6|x|12|m|ft|abbr=on}}
→ Template loop detected: Template:Convert{{convert|20|,|40|, or|60|mi}}
→ Template loop detected: Template:ConvertWhile it is possible to enter feet, inch in a simple conversion, this is not possible for ranges:
{{convert|1|ft|3|in|x|3|ft|5|in|mm}}
→ Template loop detected: Template:Convert Default behaviour, for comparison:
{{convert|1|ft|3|in|mm}}
→ Template loop detected: Template:ConvertHowever, converting metric units into feet and inches with |order=flip
can produce the desired output:
{{convert|380|x|1040|mm|ftin|order=flip}}
→ Template loop detected: Template:ConvertDefault spelling of units is in the en (generic) locale. To show en-US spelling, use |sp=us
:
{{convert|1|m|ft}}
→ Template loop detected: Template:Convert—default{{convert|1|m|ft|sp=us}}
→ Template loop detected: Template:ConvertTo write a number in words, use |spell=in
:
{{convert|10|mi|m|spell=in}}
→ Template loop detected: Template:ConvertTo spell out both in and out values, use |spell=on
:
{{convert|10|mi|m|spell=on}}
→ Template loop detected: Template:ConvertTo make first letter a capital, use |spell=In
, |spell=On
{{convert|10|mi|m|spell=In}}
→ Template loop detected: Template:Convert{{convert|10|mi|m|spell=On}}
→ Template loop detected: Template:ConvertRemember that the spelling of the units (ft, m) is independently set by |abbr=
. To the extreme:
{{convert|10|mi|m|spell=on|abbr=off|sp=us}}
→ Template loop detected: Template:Convert{{convert|4|acre||adj=pre|planted}}
→ Template loop detected: Template:Convertdisp=preunit
is similar, but has no separator after the specified text, and can have different text for the output value:
{{convert|4|acre||disp=preunit|planted }}
→ Template loop detected: Template:Convert{{convert|4|acre||disp=preunit|planted |reforested-}}
→ Template loop detected: Template:ConvertNote that two units (in this case, ft and m) are required. Use with just one unit will generate an error message.
{{convert|10|ft|m|adj=mid|-long}}
→ Template loop detected: Template:ConvertThe unit symbol is singular always. Depending on the preceding number only, a unit name can be shown plural.
{{convert|1|metre}}
→ Template loop detected: Template:Convert{{convert|2|metre}}
→ Template loop detected: Template:Convert{{convert|2|metre|abbr=on}}
→ Template loop detected: Template:ConvertEntering the unit spelled |foot|
forces singular output "foot", whatever the number is.
{{convert|100|foot|abbr=off}}
→ Template loop detected: Template:ConvertThe convert template also supports spelling out fractions.
{{convert|3+1/2|oz|g|spell=in}}
→ Template loop detected: Template:ConvertAny additional words needed for the fraction can also be added at the end of the template.
{{convert|1/8|imppt|ml|spell=in|adj=pre|of an}}
→ Template loop detected: Template:ConvertMost unit codes accept a prefix of e3 (thousand) or e6 (million) or e9 (billion).
{{convert|100|e6mi|e6km}}
→ Template loop detected: Template:Convert{{convert|120|e6acre}}
→ Template loop detected: Template:Convert{{convert|120|e6acre|e3km2}}
→ Template loop detected: Template:ConvertTo display both input and output in scientific notation, use |abbr=on
{{convert|100|e6mi|e6km|abbr=on}}
→ Template loop detected: Template:ConvertTo spell out "thousands", "millions", etc., |abbr=unit
abbreviates the unit; |abbr=off
displays both full unit names.

→ Template loop detected: Template:Convert{{convert|100|e6mi|e6km|abbr=off}}
→ Template loop detected: Template:ConvertTemplate:Sidebar metric prefixes (small)
Units can have an SI prefix like G
before the unit: Gm
, and giga
before the name: gigametre
. These are plain multiplication factors.
To illustrate, these are trivial calculations (from metre to metre), showing the multiplication factor:
The prefix can be added before the SI unit (here: unit m
for metre):
{{convert|12|Gm|mi|abbr=on}}
→ Template loop detected: Template:ConvertMm
: Template loop detected: Template:Convertkm
: Template loop detected: Template:Convertmm
: Template loop detected: Template:Convertμm
: Template loop detected: Template:Convertum
: Template loop detected: Template:Convert (letter "u" can be used for "μ" here)The prefix can be used in the output unit:
{{convert|12000|mi|Mm|abbr=on}}
→ Template loop detected: Template:Convert{{convert|12|in|μm|abbr=on}}
→ Template loop detected: Template:ConvertAs an exception, the non-SI unit "inch" can have the "μ" prefix too:
{{convert|12|μm|μin|abbr=on}}
→ Template loop detected: Template:ConvertEngineering notation can be entered as a "prefix" to the unit:
{{convert|70|e6m}}
→ Template loop detected: Template:ConvertThe same is possible for the output unit:
{{convert|23,000,000|ft|e6m}}
→ Template loop detected: Template:ConvertAny standard unit (not a combination, multiple, or built-in unit) can have such a prefix:
e3
(thousand),e6
(million),e9
(billion),e12
(trillion),e15
(quadrillion).In scientific notation, a number is written like 1.23×10−14. The plain number has exactly one digit before the decimal point.
With {{convert}}, the input can be in e-notation such as 12.3e4
. This value is displayed as a power of ten, and the output is displayed in scientific notation, except that an output value satisfying 0.01 <= v < 1000 is shown as a normal number. In addition, if the output value is 1000 and sigfig=4 is used, the value is displayed as a normal number.
{{convert|12.3e-15|atm|atm|abbr=on}}
→ Template loop detected: Template:Convert{{convert|0.00000005|atm|atm|abbr=on}}
→ Template loop detected: Template:ConvertThe number to convert can be written in fractions. Both /
(keyboard slash) and ⁄
(fraction slash) are accepted:
{{convert|1/2|in|mm|1}}
→ Template loop detected: Template:Convert{{convert|1⁄2|in|mm|1}}
→ Template loop detected: Template:ConvertWith positive mixed numbers (a positive integer and a fraction), use a +
sign
{{convert|2+1⁄2|in|mm|1}}
→ Template loop detected: Template:ConvertWith negative mixed numbers, use a hyphen -
and repeat it:
{{convert|-2-1⁄2|in|mm|1}}
→ Template loop detected: Template:ConvertNote that the following cases are not interpreted as mixed numbers:
{{convert|2-1⁄2|in|mm|1}}
→ Template loop detected: Template:Convert. This is interpreted as a range from 2 inches to 1⁄2 inch.{{convert|-2+1⁄2|in|mm|1}}
→ Template loop detected: Template:Convert This is neither a mixed number nor a range, and mathematical expressions requiring calculations are not allowed here.Using a double slash (//
) provides a horizontal fraction bar for the original (input) unit:
{{convert|1//2|in|mm|1}}
→ Template loop detected: Template:Convert{{convert|6+3//8|in|mm|1}}
→ Template loop detected: Template:ConvertUsing a negative value for |frac=
provides a horizontal fraction bar for the converted (output) unit:
{{convert|12.7|mm|frac=-2}}
→ Template loop detected: Template:Convert{{convert|161.9|mm|frac=-8}}
→ Template loop detected: Template:ConvertIn input, a comma for thousands separator is accepted but not required; a gap (space) is not accepted. In output, by default, the thousand separator is the comma:
{{convert|1234567|m|ft}}
→ Template loop detected: Template:Convert{{convert|1,234,567|m|ft}}
→ Template loop detected: Template:ConvertSet |comma=off
to remove the separator from the output:
{{convert|1234567|m|ft|comma=off}}
→ Template loop detected: Template:ConvertUse |comma=gaps
to use digit grouping by gap (thin space) as a thousands separator:
{{convert|1234567|m|ft|comma=gaps}}
→ Template loop detected: Template:ConvertDefault behaviour, for comparison:
{{convert|1234567|m|ft}}
→ Template loop detected: Template:ConvertSetting |comma=5
will only add the separator when the number of digits is 5 or more:
{{convert|1234|m|ft|comma=5}}
→ Template loop detected: Template:Convert{{convert|1234567|m|ft|comma=5}}
→ Template loop detected: Template:ConvertDefault behaviour, for comparison:
{{convert|1234|m|ft}}
→ Template loop detected: Template:ConvertPunctuation that distinguishes the two measurements is set by |disp=
.
Options are: b
(the default), sqbr
, comma
, or
, br
, br()
, x|…
:
{{convert|10|m|ft|disp=sqbr}}

→ Template loop detected: Template:ConvertDefault behaviour, for comparison:
{{convert|10|m|ft}}
→ Template loop detected: Template:ConvertSetting |disp=br
will force a new line (<br/>
)
{{convert|10|m|ft|disp=br}}
→ Template loop detected: Template:ConvertAlso |disp=br()
will force a new line, and keep the brackets (useful in tables):
{{convert|10|m|ft|disp=br()}}
→ Template loop detected: Template:ConvertSetting |disp=x|…
allows any text as separator:
{{convert|10|m|ft|disp=x|_MyText_}}
→ Template loop detected: Template:Convert (To display spaces, use
)Setting |order=flip
will flip (swap) the two measurements:
{{convert|1|mi|m|order=flip}}
→ Template loop detected: Template:ConvertDefault behaviour, for comparison:
{{convert|1|mi|m}}
→ Template loop detected: Template:ConvertWhen converting to multiple units, the effect is:
{{convert|10|km|mi nmi|order=flip}}
→ Template loop detected: Template:Convert{{convert|10|km|nmi mi|order=flip}}
→ Template loop detected: Template:ConvertSetting |order=out
shows the output-units as ordered; the input unit is skipped:
{{convert|100|C|F C K|abbr=on|order=out}}
→ Template loop detected: Template:Convert{{convert|200|PS|kW hp|0|abbr=on|order=out}}
→ Template loop detected: Template:ConvertSee also: § Displaying parts of the output.
It is possible to display only parts of the conversion result:

Setting |abbr=~
returns both name and symbol of the first (input) unit:
{{convert|2|kPa|psi|abbr=~}}
→ Template loop detected: Template:ConvertA {{convert|2|kPa|psi|abbr=~|adj=on}} pressure
→ A Template loop detected: Template:Convert pressureFor the wikitable structure, there are three options: add a line-break, split the result over columns and make the table sortable.
|disp=br
adds a line-break and omits brackets.
|disp=br()
adds a line-break and does add brackets to the converted value. This may be useful in tables:
|disp=br |
|disp=br()
|
---|---|
Template loop detected: Template:Convert | Template loop detected: Template:Convert |
Using {convert} in a table cell, with |disp=table
splits the result over two (or more) columns. By default units are not included in the table, however, they can be added using the |abbr=
parameter. Multiple-unit outputs, like ftin
, always output their units to the table.
{{convert|10|m|ft|disp=table}}
→Template loop detected: Template:Convert
|disp=tablecen
does the same, and also centers the text:
{{convert|20|m|ft|disp=tablecen}}
→Template loop detected: Template:Convert
The units are added as a column header:
kilograms | pounds | stone and pounds | |
---|---|---|---|
|disp=table
|
Template loop detected: Template:Convert | ||
|disp=table and |abbr=on
|
Template loop detected: Template:Convert | ||
|disp=table and |abbr=off
|
Template loop detected: Template:Convert | ||
|disp=tablecen
|
Template loop detected: Template:Convert | ||
|disp=<other> (default)
|
Template loop detected: Template:Convert |
Use |sortable=on
to include a hidden numerical sortkey in the output, suitable for use in a table with sortable columns. Technically, this places a hidden string before the actual displayed values:
{{convert|10|m|ft|sortable=on}}
→ <span data-sort-value="7001100000000000000♠"></span>10 metres (33 ft)
Use both |disp=table
and |sortable=on
together to produce table columns (pipe symbols) for each value in sortable columns:
m | m | ft | |
---|---|---|---|
A | 15.75 m | Template loop detected: Template:Convert | |
B | 15.5 m | Template loop detected: Template:Convert | |
C | 16 m | Template loop detected: Template:Convert | |
D | 16 m | Template loop detected: Template:Convert |
The generated sortkey is calculated in a consistent way based on both the value and its unit as passed to the convert template. In most cases convert uses the passed value converted to SI base units. It is therefore not necessarily the displayed value or other alternate units and is calculated regardless of output format options. Using different units or different order of units in individual rows should therefore not lead to incorrect sorting, although variations in rounding can give surprising results, since an unrounded number is used for the sortkey.

is recognized as kilograms per hectolitre and will be converted with other mass/volume units.

{{convert|10|C}}
→ Template loop detected: Template:Convert (standard temperature conversion){{convert|10–15|C}}
→ Template loop detected: Template:Convert (standard temperature range conversion)When expressing a temperature change (e.g., "The temperature increased by 10 °C"), or when comparing temperatures (e.g., "10 to 15 °C warmer"), we cannot use the standard temperature units (|C
, |F
and |K
), which refer to points on the respective scale. Instead, we must use one of the following "units of difference": |C-change
, |F-change
and |K-change
.

Using currency symbols in a $ per unit value, you can convert the per-unit:
{{convert|10|$/mi|$/km}}
→ Template loop detected: Template:Convert{{convert|1500|$/ozt|$/g}}
→ Template loop detected: Template:ConvertYou can set the currency in both values using |$=€
:
{{convert|10|$/mi|$/km|$=€}}
→ Template loop detected: Template:ConvertIt is not possible to convert the currency. So, this result (mixed currencies) is not possible: Template:!mxt
For usage in template code, like infoboxes, {{Convert}} has these options:
|input=16 7/8
and use {{#invoke:Convert/helper|number|16 7/8}} → 16+7/8|input=P2073
, to your template code automatically returns the Wikidata property for that article, and convert it. Both number and unit are read.Note: to return that property value for an other article, use |qid=
.
Example for (P2073):
Note: this example uses |qid=Q1056131
(testing for (Q1056131))
{{convert|input=P2073|qid=Q1056131|ftin|abbr=on}}
→ Template loop detected: Template:Convert{{convert|input=P2073|qid=Q1056131|km|abbr=on}}
→ Template loop detected: Template:Convert{{convert|input=P2073|qid=Q1056131|km|abbr=on|disp=out}}
→ Template loop detected: Template:ConvertSometimes a property may have more than one value against it in Wikidata. You can use the |qual=
parameter to specify which of the values you want to use.
Example for (P2386):
Note: this example uses |qid=Q1513315
(testing for (Q1513315))
{{convert|input=P2386|qual=Q613628|ft|abbr=on}}

Converts measurements to other units.
Parameter | Description | Type | Status | |
---|---|---|---|---|
Value | 1 | The value to convert. | Number | required |
From unit | 2 | The unit for the provided value.
| String | required |
To units | 3 | The units to convert into. Separate units by a space for multiple outputs. In an output unit, use + for a multiplication space.
| String | suggested |
Precision or suffix | 4 | Significant digits after decimal dot or, if negative, exponent of ten. | Number | optional |
Link units | lk | Indication of what units to apply wikilinks to. Use “on” for all, “in” for the input unit, “out” for the output units, or “off” for none of the units.
| String | optional |
Abbreviation | abbr | Display for the units: “on” to display all units using their unit symbols, “off” to display all units in full words, “in” to display the unit symbol for the input unit, “out” to display the unit symbols for the output units, “unit” to display unit symbols for both input and output units when using scientific notation, “values” for no units at all (neither unit symbols nor full words of units).
| String | suggested |
Spelling | sp | Spelling of units. Use “us” to display unit names using U.S. spelling.
| String | optional |
Adjective | adj | Whether to use adjectival form. Use “on” for singular unit name appended by a hyphen, “mid” to put conversion at end, or “off” (default) for no adjectival form.
| Unbalanced wikitext | optional |
Conversion | disp | Display conversion result: “or”: after ‘or’, “x”: with custom prefix and suffix, “b”: in parentheses, “table”/“tablecen”, “output only”: alone, “output number only”: alone and without unit, “unit”: not at all but input unit; if the value is a number it is used as precision.
| String | optional |
Ordering | order | “flip” returns converted value first, input value second.
| String | optional |
Significant figures | sigfig | Indicates the number of significant figures to be used in rounding. | Number | optional |
Rounding output | round | The type of rounding. “5” rounds the output number to nearest multiple of 5, “25” to nearest multiple of 25, “each” rounds each number in a range. | Number | optional |
Thousands separator | comma | Sets or suppresses the use of thousands separators in the numbers. “off”: no separator; “gaps”: use space instead of comma as thousands separator; “5”: only add thousands separator when the integral part of the number uses 5 positions or more (10,000 or more; if using comma as thousands separator, 1234 would produce '1234', 12345 would produce '12,345').
| String | optional |
Sort key | sortable | “on” generates a hidden sort key
| String | optional |
Spell numbers? | spell | If used, spells input or input and output numbers in words, optionally capitalizing the first
| String | optional |
Singular? | sing | If 'yes', uses singular form of units (deprecated)
| String | deprecated |
Fraction? | frac | fraction as rounding unit | Number | optional |
Currency symbol | $ | sets currency symbol in both units
| String | optional |
WD property | input | Reads the property value of the item (article), then converts it
| String | optional |
