Template:Convert

Template documentation[view] [edit] [history] [purge]

For currency conversion into US dollars, see Template:To USD

Template {{convert}} calculates from one measurement unit to another one, and then presents the results formatted. For example:

{{convert|2|km|mi}} → Template:Convert/km (km entered, so converted into mile)

{{convert|7|mi|km}} → Template:Convert/mi (mi entered, so converted into km)

Numbers can be rounded, units can be abbreviated into symbols:

{{convert|2|km|mi|2|abbr=on}} → Template:Convert/km

{{convert|7|mi|km|2|abbr=on}} → Template:Convert/mi

Value ranges can be entered using |to|... or |-|...:

{{convert|2|to|5|km|mi}} → Template:Convert/to

{{convert|2|-|5|km|mi}} → Template:Convert/-

Combined effect example:

{{convert|2|-|5|km|mi|2|abbr=on}} → Template:Convert/-

{{convert|2|and|5|km|mi|sigfig=3|abbr=off}} → Template:Convert/and

See Help:Convert for more detailed, technical information

Units to convert

Enter units to convert:

• {{convert|1|lb|kg}} → Template:Convert/lb

SI units generally accept prefixes, like "m" for micro (10⁻³), and "M" for mega (10⁶)

For "per" units, use "/" (slash): kg/ha

For three-unit units etc.: see Category:Convert-like templates

Unit name or symbol (abbreviation): 1 pound or 1 lb?

By default, the first quantity shows unit name, the second shows the symbol (or abbreviation):

• {{convert|1|lb|kg}} → Template:Convert/lb

Using |abbr=in is the reverse behaviour to the default:

• {{convert|1|lb|kg|abbr=in}} → Template:Convert/lb

To abbreviate both or neither:

• {{convert|1|lb|kg|abbr=on}} → Template:Convert/lb
• {{convert|1|lb|kg|abbr=off}} → Template:Convert/lb

When using scientific notation, the default is for the second (converted) quantity to be displayed using scientific notation:

• {{convert|100|e6mi|e6km}} → Template:Convert/e6mi

To display thousands, millions, etc., while abbreviating both input and output units use |abbr=unit:

• {{convert|100|e6mi|e6km|abbr=unit}} → Template:Convert/e6mi

Convenience: {{cvt}} has |abbr=on by default

Template {{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)

Adjective: a 10-mile distance

Use |adj=on to produce the adjectival (hyphenated) form:

• A {{convert|10|mi|km|adj=on}} distance → A Template:Convert/mi distance.

Default behaviour, for comparison:

• {{convert|10|mi|km}} to go → Template:Convert/mi to go.

Even with |abbr=on, as per MoS no hyphen is produced with unit symbols.

Rounding: 100 ft is 30 m or 30.5 m or 30.48 m?

By definition, 100 ft equals Template:Convert/ft. In practical use, it is common to round the calculated metric number. With that, there are several possibilities.

Default rounding

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 figures, whichever is more precise. An exception to this is rounding temperatures (see below).

Examples of rounding
Input	Displays as	Note
{{convert|123|ft|m|-1}}	Template:Convert/ft
{{convert|123|ft|m}}	Template:Convert/ft	same output as with 0 (below)
{{convert|123|ft|m|0}}	Template:Convert/ft
{{convert|123|ft|m|1}}	Template:Convert/ft
{{convert|123|ft|m|2}}	Template:Convert/ft	exact value is 37.4904 m
{{convert|500|ft|m|-1}}	Template:Convert/ft
{{convert|500|ft|m}}	Template:Convert/ft	same output as with -1 (above)
{{convert|500|ft|m|0}}	Template:Convert/ft
{{convert|500|ft|m|1}}	Template:Convert/ft
{{convert|500|ft|m|2}}	Template:Convert/ft	exact value is 152.4 m
{{convert|500|ft|cm}}	Template:Convert/ft	different output as with 0 (below)
{{convert|500|ft|cm|0}}	Template:Convert/ft

Convert supports four types of rounding:

Round to a given precision: use a precision number

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 1⁄10 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.

Round to a given number of significant figures: |sigfig=

To specify the output number to be with n significant figures use |sigfig=<number>:

• {{convert|1200|ft|m|sigfig=4}} → Template:Convert/ft
• {{convert|1200|ft|m|sigfig=3}} → Template:Convert/ft
• {{convert|1200|ft|m|sigfig=2}} → Template:Convert/ft
• {{convert|1200|ft|m|sigfig=1}} → Template:Convert/ft

Default behaviour, for comparison:

• {{convert|1200|ft|m}} → Template:Convert/ft

Setting |sigfig= to a value less than 1 is meaningless:

• {{convert|1200|ft|m|sigfig=0}} → Template:Convert/ft Red XN

Round to a multiple of 5: 15, 20, 25, ...

Using |round=5 rounds the outcome to a multiple of 5.

• {{convert|10|m|ft}} → Template:Convert/m
• {{convert|10|m|ft|round=5}} → Template:Convert/m

Similar: using |round=25 rounds the outcome to a multiple of 25.

• {{convert|10|m|ft}} → Template:Convert/m
• {{convert|10|m|ft|round=25}} → Template:Convert/m

Default behaviour, for comparison:

• {{convert|10|m|ft|sigfig=4}} → Template:Convert/m

In a range, one can round each value individually to the default. Use |round=each:

• {{convert|10 x 200 x 3000|m|ft}} → Template:Convert/m
• {{convert|10 x 200 x 3000|m|ft|round=each}} → Template:Convert/m

Round to a multiple of a given fraction: 2+3⁄16 inch

Specify the desired denominator using |frac=<some positive integer>. (Denominator is the below-the-slash number, for example the 3 in 1⁄3).

• {{convert|5.56|cm|in|frac=16}} → Template:Convert/cm
• {{convert|8|cm|in|frac=4}} → Template:Convert/cm

The fraction is reduced when possible:

• {{convert|8|cm|in|frac=100}} → Template:Convert/cm

Default behaviour uses decimal notation:

• {{convert|5.56|cm|in}} → Template:Convert/cm

Rounding temperatures: °C, °F and K

In temperatures, the conversion will be rounded either to 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.

1. {{convert|10,000|C|F K}} → Template:Convert/C
2. {{convert|10,000.1|C|F K}} → Template:Convert/C
3. {{convert|-272|C|F K}} → Template:Convert/C
4. {{convert|-272|C}} → Template:Convert/C
5. {{convert|-300|C|F K}} → Template:Convert/C
6. {{convert|0|C|F K}} → Template:Convert/C

The 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:Convert/C-change, 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:Convert/C

or you set the precision positionally, relative to the decimal point (zero being at the decimal point):

{{convert|10000|C|0}} → Template:Convert/C

The 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.

Rounding input

There is limited support for rounding the displayed input number. The rounding tales place after conversion, so the output is based on the full-precision input. This is useful when the input is produced by {{#expr:}} 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-1Red XN 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:

• {{convert|4.14159|mi|km|adj=ri0}} → Template:Convert/mi
• {{convert|4.14159|mi|km|0|adj=ri0}} → Template:Convert/mi

In this case, if the input were rounded before conversion, a different result would be obtained:

• {{convert|{{#expr:4.14159 round 0}}|mi|km|0}} → Template:Convert/mi

Into multiple units: Template:Convert/C

Separate the multiple output units by a space:

• {{convert|10|C|F K}} → Template:Convert/C
• {{convert|5|km|mi nmi}} → Template:Convert/km

If the output unit names contain spaces, use + as the separator.

• For multiple-unit options like 1 ft 5 in, see § In input and § In output.

Ranges of values

For a conversion of a difference, see § Units of difference.

A range converts two values and separates them by your choice of words and punctuation.

A range: 6 to 17 kg (13 to 37 lb)

Range indicators are entered as the second parameter (between the values). Range separators can be:

Range separators in {{convert}}

*	|*| is deprecated. Use |x| instead

Multiple dimensions: Template:Convert/x

Use by:

• {{convert|6|by|12|ft|m}} → Template:Convert/by

Use ×, multiplication sign, or x, letter:

• {{convert|6|x|12|m|ft}} → Template:Convert/x

In 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:Convert/x

About feet, inch in ranges and multiples

While 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:Convert/ft Red XN

Default behaviour, for comparison:

• {{convert|1|ft|3|in|mm}} → Template:Convert/ft

Words

Spelling of unit name: UK metre or US meter?

Default spelling of units is en-UK. To show en-US spelling, use |sp=us:

{{convert|1|m|ft}} → Template:Convert/m—default

{{convert|1|m|ft|sp=us}} → Template:Convert/m

Spell out numbers: ten miles

To write a number in words, use |spell=in:

• {{convert|10|mi|m|spell=in}} → Template:Convert/mi

To spell out both in and out values, use |spell=on:

• {{convert|10|mi|m|spell=on}} → Template:Convert/mi

To make first letter a capital, use |spell=In, |spell=On

• {{convert|10|mi|m|spell=In}} → Template:Convert/mi
• {{convert|10|mi|m|spell=On}} → Template:Convert/mi

Remember 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:Convert/mi

Inserted before units: 4 planted acres

• {{convert|4|acre||adj=pre|planted}} → Template:Convert/acre

disp=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:Convert/acre
• {{convert|4|acre||disp=preunit|planted |reforested-}} → Template:Convert/acre

After adjective unit: A Template:Convert/ft corridor

{{convert|10|ft|m|adj=mid|-long}} → Template:Convert/ft

Plurals: 1 inch, 2 inches

The unit symbol is singular always. Depending on the preceding number only, a unit name can be shown plural.

• {{convert|1|metre}} → Template:Convert/metre
• {{convert|2|metre}} → Template:Convert/metre
• {{convert|2|metre|abbr=on}} → Template:Convert/metre

Exception

Entering the unit spelled |foot| forces singular output "foot", whatever the number is.

• {{convert|100|foot|abbr=off}} → Template:Convert/foot

Fractions: one-eighth of an imperial pint

The convert template also supports spelling out fractions.

• {{convert|3+1/2|oz|g|spell=in}} → Template:Convert/oz

Any 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:Convert/imppt

Wrapping and line breaking

Numbers

Using an SI prefix: gigameter (Gm), or micrometer (μm)

Metric prefixes
Text Symbol Factor yotta Y 1024 zetta Z 1021 exa E 1018 peta P 1015 tera T 1012 giga G 109 mega M 106 kilo k 103 hecto h 102 deca da 101 (none) (none)  1 deci d 10−1 centi c 10−2 milli m 10−3 micro μ 10−6 nano n 10−9 pico p 10−12 femto f 10−15 atto a 10−18 zepto z 10−21 yocto y 10−24

Units can have an SI prefix like G before the unit: Gm, and giga before the name: gigameter. These are plain multiplication factors.

To illustrate, these are trivial calculations (from meter to meter), showing the multiplication factor:

• Template:Convert/Gm
• Template:Convert/μm

The prefix can be added before the SI unit (here: unit m for meter):

• {{convert|12|Gm|mi|abbr=on}} → Template:Convert/Gm
• Mm: Template:Convert/Mm
• km: Template:Convert/km
• mm: Template:Convert/mm
• μm: Template:Convert/μm
• um: Template:Convert/um (letter "u" can be used for "μ" here)

The prefix can be used in the output unit:

• {{convert|12000|mi|Mm|abbr=on}} → Template:Convert/mi
• {{convert|12|in|μm|abbr=on}} → Template:Convert/in

As an exception, the non-SI unit "inch" can have the "μ" prefix too)

• {{convert|12|μm|μin|abbr=on}} → Template:Convert/μm

Further information: Help:Convert units § SI prefixes

Engineering notation: 7 × 10⁶ m

In the unit: e6m

Engineering number notations like 7E6 (for 7 × 10⁶) can be entered as a "prefix" to the unit:

• {{convert|7|e6m}} → Template:Convert/e6m

The same is possible for the output unit:

• {{convert|23,000,000|ft|e6m}} → Template:Convert/ft

Any 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).

Scientific notation: 1.23 × 10⁻¹⁴

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:Convert/atm
• {{convert|0.00000005|atm|atm|abbr=on}} → Template:Convert/atm

Input with fractions: Template:Convert/in

The number to convert can be written in fractions. Both / (keyboard slash) and ⁄ (fraction slash) are accepted:

• {{convert|1/2|in|mm|1}} → Template:Convert/in
• {{convert|1⁄2|in|mm|1}} → Template:Convert/in

With integers, use a + sign

• {{convert|2+1⁄2|in|mm|1}} → Template:Convert/in

When negative, use a hyphen - and repeat it:

• {{convert|-2-1⁄2|in|mm|1}} → Template:Convert/in
• {{convert|2-1⁄2|in|mm|1}} → Template:Convert/in Note: this is read as a range
• {{convert|-2+1⁄2|in|mm|1}} → Template:Convert/in Red XN Should be a number, not an expression (do not require a calculation)

Output with horizontal fraction bar in: 1/2 inch

Using a double slash (//) returns a horizontal bar fraction:

• {{convert|1//2|in|mm|1}} → Template:Convert/in
• {{convert|2+1//2|in|mm|1}} → Template:Convert/in

Thousands separator: 1,000 mi or 1000 mi

In 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:Convert/m
• {{convert|1,234,567|m|ft}} → Template:Convert/m
• {{convert|1 234 567|m|ft}} → Template:Convert/m Red XN

Set |comma=off to remove the separator from the output:

• {{convert|1234567|m|ft|comma=off}} → Template:Convert/m

Use |comma=gaps to use digit grouping by gap (thin space) as a thousands separator:

• {{convert|1234567|m|ft|comma=gaps}} → Template:Convert/m

Default behaviour, for comparison:

• {{convert|1234567|m|ft}} → Template:Convert/m

Setting |comma=5 will only add the separator when the number of digits is 5 or more:

• {{convert|1234|m|ft|comma=5}} → Template:Convert/m
• {{convert|1234567|m|ft|comma=5}} → Template:Convert/m

Default behaviour, for comparison:

• {{convert|1234|m|ft}} → Template:Convert/m

Output manipulation

Brackets and separators: 10 m [33 ft]

Punctuation that distinguishes the two measurements is set by |disp=.
Options are: b (the default), sqbr, comma, or, br, x|…:

• {{convert|10|m|ft|disp=sqbr}} → Template:Convert/m
• {{convert|10|m|ft|disp=comma}} → Template:Convert/m
• {{convert|10|m|ft|disp=or}} → Template:Convert/m

Default behaviour, for comparison:

• {{convert|10|m|ft}} → Template:Convert/m

Setting |disp=br will force a new line (<br/>)

• {{convert|10|m|ft|disp=br}} → Template:Convert/m

Also |disp=br() will force a new line, and keep the brackets (useful in tables):

• {{convert|10|m|ft|disp=br()}} → Template:Convert/m

Setting |disp=x|… allows any text as separator:

• {{convert|10|m|ft|disp=x|_MyText_}} → Template:Convert/m (To display spaces, use  )

Flipping (reordering) the two measurements: Template:Convert/mi

Setting |order=flip will flip (swap) the two measurements:

• {{convert|1|mi|m|order=flip}} → Template:Convert/mi

Default behaviour, for comparison:

• {{convert|1|mi|m}} → Template:Convert/mi

When converting to multiple units, the effect is:

• {{convert|10|km|mi nmi|order=flip}} → Template:Convert/km
• {{convert|10|km|nmi mi|order=flip}} → Template:Convert/km

Displaying parts of the result: Template:Convert/cuyd

It is possible to display only parts of the conversion result:

Convert	Output	Description
{{convert|2|cuyd|m3}}	Template:Convert/cuyd	Default behaviour, for comparison
{{convert|2|cuyd|m3|abbr=values}}	Template:Convert/cuyd	Input and output numbers
{{convert|2|cuyd|m3|disp=unit}}	Template:Convert/cuyd	Input unit
{{convert|2|cuyd|m3|disp=unit|adj=on}}	Template:Convert/cuyd	Input unit, adjective (hyphenated)
{{convert|2|cuyd|cuyd|disp=out}}	Template:Convert/cuyd	Input (workaround. Note repetition of unit in input)
{{convert|2|cuyd|m3|abbr=~}}	Template:Convert/cuyd	Input: both name and symbol
{{convert|2|cuyd|m3|disp=unit2}}	Template:Convert/cuyd	Output unit (symbol)
{{convert|2|cuyd|m3|disp=unit2|abbr=off}}	Template:Convert/cuyd	Output unit (name)
{{convert|2|cuyd|m3|disp=number}}	Template:Convert/cuyd	Output value
{{convert|2|cuyd|m3|disp=out}}	Template:Convert/cuyd	Output value and unit
{{convert|2|cuyd|m3|disp=out|abbr=off}}	Template:Convert/cuyd	Output value and unit

Display both input name and symbol: 2 kilopascals [kPa]

Setting |abbr=~ returns both name and symbol of the first (input) unit:

• {{convert|2|kPa|psi|abbr=~}} → Template:Convert/kPa
• A {{convert|2|kPa|psi|abbr=~|adj=on}} pressure → A Template:Convert/kPa pressure

Table options

For the wikitable structure, there are three options: add a line-break, split the result over columns and make the table sortable.

Enforced line break

|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:Convert/km	Template:Convert/km

Table columns showing numbers only

Using {convert} in a table cell, with |disp=table splits the result over two columns:

{{convert|10|m|ft|disp=table}} →

Template:Convert/m

|disp=tablecen does the same, and also centers the text:

{{convert|20|m|ft|disp=tablecen}} →

Template:Convert/m

The units are added as a column header:

	m	ft
|disp=table	Template:Convert/m
|disp=tablecen	Template:Convert/m
|disp=<other> (default)	Template:Convert/m

Sorting

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 style="display:none">7001100000000000000</span>10 metres (33&nbsp;ft)

Use both |disp=table and |sortable=on together to produce table columns (pipe symbols) for each value in sortable columns:

	m	ft
A	0000000000015.75Template:Convert/m
B	00000000000015.5Template:Convert/m
C	0000000000000016Template:Convert/m
D	0000000000000016Template:Convert/m

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.

Units

All units

Units are case-sensitive: use kW, not KW or kw

The table below lists units supported by template {{convert}}. The list is not complete—more complete lists are linked for each dimension. A complete list is at the full list of units.

Explanation – unit codes

The {{convert}} template uses unit-codes, which are similar to (but not necessarily exactly the same as) the usual written abbreviation for a given unit. These 'unit-codes' are given in column 3 of the following tables, and are accepted as input by the {{convert}} template as the second and third unnamed parameters. For example, {{convert|100|kg|lb}} produces "Template:Convert/kg" and {{convert|100|lb|kg}} produces "Template:Convert/lb"

Some units have alternative unit-codes; these are shown in brackets in column 3, e.g. °F (F): either may be entered for Fahrenheit (but not lower-case f).

The unit-codes should be treated as case-sensitive, especially in cases like {{convert|100|Mm|mm}}, which produces "Template:Convert/Mm".

The output of {{convert}} can display multiple converted units, if further unit-codes are specified after the second unnamed parameter (without the | separator). Typical combination output units are listed below in column 7. For example, {{convert|55|nmi|km mi}} produces "Template:Convert/nmi", and {{convert|1|oz|ozt g gr}} produces "Template:Convert/oz".

'per' units: kg/hl

When using a slash (/), a unit like kg/hl is recognized as kilograms per hectolitre and will be converted with other mass/volume units.

• {{convert|1000|kg/hl}} → Template:Convert/kg/hl

Units of difference: 10 °C higher; how much in °F

When a number is the measurement for a difference, one conversion is done. This may occur in temperatures (°C, °F, K). Compare this to a range, when two conversions are done.

The only available units of difference are: |C-change=, |F-change= and |K-change=.

• {{convert|10|C}} → Template:Convert/C, regular temperature
• {{convert|10|C-change}} → Template:Convert/C-change, difference (e.g., "The temperature changed from 30 into 40 °C")
• {{convert|10-15|C}} → Template:Convert/C, range (e.g., "The temperature is between 10 and 15 °C")

Consistently, into multiple units:

• A rise of {{convert|10|C-change|F-change K-change}} → A rise of Template:Convert/C-change

Multiple units: 1 ft 5 in

In input

Base document § Input multiples lists options for multiple unit input (like ft,in). It can catch predefined sets only (units that can be subdivided; e.g., yd into ft):

• {{convert|1|yd|2|ft|3|in}} → Template:Convert/yd
• {{convert|2|ft|3|in|cm}} → Template:Convert/ft
• {{convert|1|lb|5|oz|g}} → Template:Convert/lb

In output

Available multiple-unit output options predefined, like ftin and ydftin. The full list is at § Output multiples.

• {{convert|2|m|ftin}} → Template:Convert/m
• {{convert|2|m|ft in}} → Template:Convert/m, using a space, returns the decimal point

Default behaviour, for comparison:

• {{convert|2|m}} → Template:Convert/m

• {{hands}} a length used to measure horses
• {{Long ton}} a weight in ton, cwt, qr and lb

Currency per unit: $/mi → $/km

Using currency symbols in a $ per unit value, you can convert the per-unit:

• {{convert|10|$/mi|$/km}} → Template:Convert/$/mi

You can set the currency in both values using |$=€:

• {{convert|10|$/mi|$/km|$=€}} → Template:Convert/$/mi

It is not possible to convert the currency. So, this result (mixed currencies) is not possible: $15 per mile (€8.6/km) Red XN

Using convert inside templates

For usage in template code, like infoboxes, {{Convert}} has these options:

Pre-formatting fraction input

• Module:Convert/helper can read regular input and pre-format it into {{Convert}}-accepted input.

Your template can accept |input=16 7/8 and use {{#invoke:Convert/helper|number|16 7/8}} → 16+7/8

Using a Wikidata property

• Adding the Wikidata property code, like code |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}} → {{convert/{{{2}}}|ftin|0|||||r=re|d=LoffAonDbSoff|s=}}
• {{convert|input=P2073|qid=Q1056131|km|abbr=on}} → {{convert/{{{2}}}|km|0|||||r=re|d=LoffAonDbSoff|s=}}
• {{convert|input=P2073|qid=Q1056131|km|abbr=on|disp=out}} → {{convert/{{{2}}}|km|0|||||r=re|d=LoffAonDoutSoff|s=}}

For example see template:Infobox Telescope.
