Template {{convert}} calculates a measurement value (number × unit) into the same measurement by a different unit, and then presents the results, formatted. See also the unit symbols recognized by this template.
For example:
{{convert|2|km|mi}}
→ 2 kilometres (1.2 mi) (km entered, converted into miles){{convert|7|mi|km}}
→ 7 miles (11 km) (mi entered, converted into km)Numbers can be rounded, units can be abbreviated into symbols:
{{convert|2|km|mi|2|abbr=on}}
→ 2 km (1.24 mi){{convert|7|mi|km|2|abbr=on}}
→ 7 mi (11.27 km)
Value ranges can be entered using |to|...
or|-|...
:
{{convert|2|to|5|km|mi}}
→ 2 to 5 kilometres (1.2 to 3.1 mi){{convert|2|-|5|km|mi}}
→ 2–5 kilometres (1.2–3.1 mi)Combined effect example:
{{convert|2|-|5|km|mi|2|abbr=on}}
→ 2–5 km (1.24–3.11 mi){{convert|2|and|5|km|mi|sigfig=3|abbr=off}}
→ 2 and 5 kilometres (1.24 and 3.11 miles)Enter units to convert from into:
{{convert|1|lb|kg}}
→ 1 pound (0.45 kg)By default, the first quantity shows the unit name, the second shows the symbol (or abbreviation):
{{convert|1|lb|kg}}
→ 1 pound (0.45 kg)
Using |abbr=in
shows the symbol for first (left-hand side) unit, and the name instead of the symbol for the second unit:
{{convert|1|lb|kg|abbr=in}}
→ 1 lb (0.45 kilograms)To abbreviate both or neither:
{{convert|1|lb|kg|abbr=on}}
→ 1 lb (0.45 kg){{convert|1|lb|kg|abbr=off}}
→ 1 pound (0.45 kilograms)|abbr=on
by default
Template {{cvt}} is the same as {{convert}}, except that it has |abbr=on
as the default behavior. 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 10-mile (16 km) distance.Default behavior, for comparison:
{{convert|10|mi|km}} to go
→ 10 miles (16 km) to go.
|adj=on
does not produce hyphens with unit symbols, as per Manual of Style:
A {{convert|9|in|cm|adj=on|abbr=on}} nail
→ A 9 in (23 cm) nail.By definition, 100 ft equals 30.48 m. 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).
Examples of rounding
Input
Displays as
Note
{{convert|123|ft|m|-1}}
123 feet (40 m)
{{convert|123|ft|m}}
123 feet (37 m)
same output as with 0 (below)
{{convert|123|ft|m|0}}
123 feet (37 m)
{{convert|123|ft|m|1}}
123 feet (37.5 m)
{{convert|123|ft|m|2}}
123 feet (37.49 m)
123 feet is exactly 37.4904 m which is rounded to 37 m if this parameter is not specified at all
{{convert|500|ft|m|-1}}
500 feet (150 m)
{{convert|500|ft|m}}
500 feet (150 m)
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}}
500 feet (152 m)
{{convert|500|ft|m|1}}
500 feet (152.4 m)
{{convert|500|ft|m|2}}
500 feet (152.40 m)
exact value is 152.4 m
{{convert|500|ft|cm|-3}}
500 feet (15,000 cm)
{{convert|500|ft|cm}}
500 feet (15,000 cm)
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}}
500 feet (15,240 cm)
Convert supports four types of rounding:
Specify the desired precision with an integer as 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 integer. For instance, if the result is 8621 and the rounding parameter is "−2", 8600 will be displayed. If the result is "123.456" and the parameter is "0", 123 will be displayed. Essentially a positive or zero rounding parameter specifies the number of decimal places; a negative value specifies the number of trailing zeroes.
|sigfig=
To specify the output number to be with n significant figures use |sigfig=<number>
:
{{convert|1200|ft|m|sigfig=4}}
→ 1,200 feet (365.8 m){{convert|1200|ft|m|sigfig=3}}
→ 1,200 feet (366 m){{convert|1200|ft|m|sigfig=2}}
→ 1,200 feet (370 m){{convert|1200|ft|m|sigfig=1}}
→ 1,200 feet (400 m)Default behavior, for comparison:
{{convert|1200|ft|m}}
→ 1,200 feet (370 m)
Setting |sigfig=
to a value less than 1 is meaningless:
{{convert|1200|ft|m|sigfig=0}}
→ 1,200 feet (370 m)* N
Using |round=5
rounds the outcome to a multiple of 5.
{{convert|10|m|ft}}
→ 10 metres (33 ft){{convert|10|m|ft|round=5}}
→ 10 metres (35 ft)
Similar: using |round=25
rounds the outcome to a multiple of 25.
{{convert|10|m|ft}}
→ 10 metres (33 ft){{convert|10|m|ft|round=25}}
→ 10 metres (25 ft)Default behavior, for comparison:
{{convert|10|m|ft|sigfig=4}}
→ 10 metres (32.81 ft)
In a range, one can round each value individually to the default. Use |round=each
:
{{convert|10 x 200 x 3000|m|ft}}
→ 10 by 200 by 3,000 metres (33 ft × 656 ft × 9,843 ft){{convert|10 x 200 x 3000|m|ft|round=each}}
→ 10 by 200 by 3,000 metres (33 ft × 660 ft × 9,800 ft)
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}}
→ 5.56 centimetres (2+3⁄16 in){{convert|8|cm|in|frac=4}}
→ 8 centimetres (3+1⁄4 in)The fraction is reduced when possible:
{{convert|8|cm|in|frac=100}}
→ 8 centimetres (3+3⁄20 in)Default behavior uses decimal notation:
{{convert|5.56|cm|in}}
→ 5.56 centimetres (2.19 in)In 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}}
→ 10,000 °C (18,000 °F; 10,300 K){{convert|10,000.1|C|F K}}
→ 10,000.1 °C (18,032.2 °F; 10,273.2 K){{convert|-272|C|F K}}
→ −272 °C (−457.60 °F; 1.15 K){{convert|-272|C}}
→ −272 °C (−457.60 °F){{convert|100|C|F K}}
→ 100 °C (212 °F; 373 K){{convert|0|C|F K}}
→ 0 °C (32 °F; 273 K)
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 0.1 degrees Celsius change is a 0.18 degrees Fahrenheit 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}}
→ 10,000 °C (18,032 °F)or you set the precision positionally, relative to the decimal point (zero being at the decimal point):
{{convert|10000|C|0}}
→ 10,000 °C (18,032 °F)The precision of the input number in example (2) is six, so the precision of the Fahrenheit output is six now, 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 the 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 {{#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 it is not possible to round above the decimal place (|adj=ri-1
N is invalid). Neither is there support for significant figures, multiples of a number, 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}}
→ 4 miles (6.66524 km) N (precisions are mismatched){{convert|4.14159|mi|km|0|adj=ri0}}
→ 4 miles (7 km) YIn this case, if the input were rounded before conversion, a different result would be obtained:
{{convert|{{#expr:4.14159 round 0}}|mi|km|0}}
→ 4 miles (6 km) N (rounds intermediate calculation, giving a different result)Separate the multiple output units by a space:
{{convert|10|C|F K}}
→ 10 °C (50 °F; 283 K){{convert|5|km|mi nmi}}
→ 5 kilometres (3.1 mi; 2.7 nmi)
If the output unit names contain spaces, use +
as the separator.

Arange 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:

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}}
→ 6 m × 12 m (20 ft × 39 ft){{convert|20|,|40|, or|60|mi}}
→ 20, 40, or 60 miles (32, 64, or 97 km)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}}
→ 1 foot 3 inches ([convert: unknown unit])* NDefault behavior, for comparison:
{{convert|1|ft|3|in|mm}}
→ 1 foot 3 inches (380 mm)
However, converting metric units into feet and inches with |order=flip
can produce the desired output:
{{convert|380|x|1040|mm|ftin|order=flip}}
→ 1 foot 3 inches by 3 feet 5 inches (380 mm × 1,040 mm)
Default spelling of units is in the en (generic) locale. To show en-US spelling, use |sp=us
:
{{convert|1|m|ft}}
→ 1 metre (3.3 ft)—default{{convert|1|m|ft|sp=us}}
→ 1 meter (3.3 ft)
To write a number in words, use |spell=in
:
{{convert|10|mi|m|spell=in}}
→ ten miles (16,000 m)
To spell out both in and out values, use |spell=on
:
{{convert|10|mi|m|spell=on}}
→ ten miles (sixteen thousand metres)
To make the first letter a capital, use |spell=In
, |spell=On
{{convert|10|mi|m|spell=In}}
→ Ten miles (16,000 m){{convert|10|mi|m|spell=On}}
→ Ten miles (sixteen thousand metres){{convert|4|acre||adj=pre|planted}}
→ 4 planted acres (1.6 ha)
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 }}
→ 4 planted acres (1.6 planted ha){{convert|4|acre||disp=preunit|planted |reforested-}}
→ 4 planted acres (1.6 reforested-ha)Note 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}}
→ 10-foot-long (3.0 m)The unit symbol is singular always. Depending on the preceding number only, a unit name can be shown plural.
{{convert|1|metre}}
→ 1 metre (3 ft 3 in){{convert|2|metre}}
→ 2 metres (6 ft 7 in){{convert|2|metre|abbr=on}}
→ 2 m (6 ft 7 in)Entering the unit "foot" instead of "ft" forces singular output "foot", whatever the number is.
{{convert|100|foot|abbr=off}}
→ 100 foot (30 metres)The convert template also supports spelling out fractions.
{{convert|3+1/2|oz|g|spell=in}}
→ three and a half ounces (99 g)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}}
→ one-eighth of an imperial pint (71 ml)Most unit codes accept a prefix of e3 (thousand) or e6 (million) or e9 (billion).
{{convert|100|e6mi|e6km}}
→ 100 million miles (160×10{{convert|120|e6acre}}
→ 120 million acres (490,000 km2){{convert|120|e6acre|e3km2}}
→ 120 million acres (490×10
To display both input and output in scientific notation, use |abbr=on
{{convert|100|e6mi|e6km|abbr=on}}
→ 100×10
To spell out "thousands", "millions", etc., |abbr=unit
abbreviates the unit; |abbr=off
displays both full unit names.
{{convert|100|e6mi|e6km|abbr=unit}}
→ 100 million mi (160 million km){{convert|100|e6mi|e6km|abbr=off}}

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}}
→ 12 Gm (7,500,000 mi)Mm
: 12 Mm (7,500 mi)km
: 12 km (39,000 ft)mm
: 12 mm (0.47 in)μm
: 12 μm (0.012 mm)um
: 12 μm (0.012 mm) (letter "u" can be used for『μ』here)The prefix can be used in the output unit:
{{convert|12000|mi|Mm|abbr=on}}
→ 12,000 mi (19 Mm){{convert|12|in|μm|abbr=on}}
→ 12 in (300,000 μm)As an exception, the non-SI unit "inch" can have the『μ』prefix too:
{{convert|12|μm|μin|abbr=on}}
→ 12 μm (470 μin)Engineering notation can be entered as a "prefix" to the unit:
{{convert|70|e6m}}
→ 70×10The same is possible for the output unit:
{{convert|23,000,000|ft|e6m}}
→ 23,000,000 feet (7.0×10Any 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).Inscientific 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}}
→ 12.3×10−15 atm (1.23×10−14 atm){{convert|0.00000005|atm|atm|abbr=on}}
→ 0.00000005 atm (5.0×10−8 atm)
The number to convert can be written in fractions. Both /
(keyboard slash) and ⁄
(fraction slash) are accepted:
{{convert|1/2|in|mm|1}}
→ 1⁄2 inch (12.7 mm){{convert|1⁄2|in|mm|1}}
→ 1⁄2 inch (12.7 mm)
With positive mixed numbers (a positive integer and a fraction), use a +
sign
{{convert|2+1⁄2|in|mm|1}}
→ 2+1⁄2 inches (63.5 mm)
With negative mixed numbers, use a hyphen -
and repeat it:
{{convert|-2-1⁄2|in|mm|1}}
→ −2+1⁄2 inches (−63.5 mm)Note that the following cases are not interpreted as mixed numbers:
{{convert|2-1⁄2|in|mm|1}}
→ 2–1⁄2 inch (50.8–12.7 mm). This is interpreted as a range from 2 inches to 1⁄2 inch.{{convert|-2+1⁄2|in|mm|1}}
→ [convert: invalid number] N This is neither a mixed number nor a range, and mathematical expressions requiring calculations are not allowed here.{{convert|2+½|in|mm|1}}
→ [convert: invalid number] N Fractions consisting of a single Unicode character are not allowed either.
Using a double slash (//
) provides a horizontal fraction bar for the original (input) unit:
{{convert|1//2|in|mm|1}}
→ 1/2 inch (12.7 mm){{convert|6+3//8|in|mm|1}}
→ 6+3/8 inches (161.9 mm)
Using a negative value for |frac=
provides a horizontal fraction bar for the converted (output) unit:
{{convert|12.7|mm|frac=-2}}
→ 12.7 millimetres (1/2 in){{convert|161.9|mm|frac=-8}}
→ 161.9 millimetres (6+3/8 in)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}}
→ 1,234,567 metres (4,050,417 ft){{convert|1,234,567|m|ft}}
→ 1,234,567 metres (4,050,417 ft)
Set |comma=off
to remove the separator from the output:
{{convert|1234567|m|ft|comma=off}}
→ 1234567 metres (4050417 ft)
Use |comma=gaps
to use digit grouping by gap (thin space) as a thousands separator:
{{convert|1234567|m|ft|comma=gaps}}
→ 1234567 metres (4050417 ft)Default behavior, for comparison:
{{convert|1234567|m|ft}}
→ 1,234,567 metres (4,050,417 ft)
Setting |comma=5
will only add the separator when the number of digits is 5 or more:
{{convert|1234|m|ft|comma=5}}
→ 1234 metres (4049 ft){{convert|1234567|m|ft|comma=5}}
→ 1,234,567 metres (4,050,417 ft)Default behavior, for comparison:
{{convert|1234|m|ft}}
→ 1,234 metres (4,049 ft)
Punctuation that distinguishes the two measurements is set by |disp=
.
Options are: b
(the default), sqbr
, comma
, semicolon
, or
, br
, br()
, x|…
:
{{convert|10|m|ft|disp=sqbr}}
→ 10 metres [33 ft]{{convert|10|m|ft|disp=comma}}
→ 10 metres, 33 ft{{convert|10|m|ft|disp=semicolon}}
→ 10 metres; 33 ft{{convert|10|m|ft|disp=or}}
→ 10 metres or 33 feetDefault behavior, for comparison:
{{convert|10|m|ft}}
→ 10 metres (33 ft)
Setting |disp=br
will force a new line (<br/>
)
{{convert|10|m|ft|disp=br}}
→ 10 metres
Also |disp=br()
will force a new line, and keep the brackets (useful in tables):
{{convert|10|m|ft|disp=br()}}
→ 10 metres
Setting |disp=x|…
allows any text as separator:
{{convert|10|m|ft|disp=x|_MyText_}}
→ 10 metres_MyText_33 ft(To display spaces, use

Setting |order=flip
will flip (swap) the two measurements:
{{convert|1|mi|m|order=flip}}
→ 1,609.3 metres (1 mile)Default behavior, for comparison:
{{convert|1|mi|m}}
→ 1 mile (1,609.3 metres)When converting to multiple units, the effect is:
{{convert|10|km|mi nmi|order=flip}}
→ 6.2137 miles; 5.3996 nautical miles (10 kilometres){{convert|10|km|nmi mi|order=flip}}
→ 5.3996 nautical miles; 6.2137 miles (10 kilometres)
Setting |order=out
shows the output-units as ordered; the input unit is skipped:
{{convert|100|C|F C K|abbr=on|order=out}}
→ 212 °F (100 °C; 373 K){{convert|200|PS|kW hp|0|abbr=on|order=out}}
→ 147 kW (197 hp)See also: § Displaying parts of the output.

Setting |abbr=~
returns both name and symbol of the first (input) unit:
{{convert|2|kPa|psi|abbr=~}}
→ 2 kilopascals [kPa] (0.29 psi)A {{convert|2|kPa|psi|abbr=~|adj=on}} pressure
→ A 2-kilopascal [kPa] (0.29 psi) 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()
100 kilometres
62 miles
100 kilometres
(62 miles)
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}}
→
style="text-align:right;"|10
|style="text-align:right;"|33
|disp=tablecen
does the same, and also centers the text:
{{convert|20|m|ft|disp=tablecen}}
→
style="text-align:center;"|20
|style="text-align:center;"|66
The units are added as a column header:
kilograms
pounds
stone and pounds
|disp=table
10
22
1 st 8 lb
|disp=table
and |abbr=on
20 kg
44 lb
3 st 2 lb

and |abbr=off
30 kilograms
66 pounds
4 stone 10 pounds
|disp=tablecen
40
88
6 st 4 lb
|disp=<other>
(default)
50 kilograms (110 lb; 7 st 12 lb)
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
15+3⁄4
52
B
15.5 m
15.5
51
C
16 m
16.0
52.5
D
16 m
16
52
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.
The conversion factors and physical constants are sourced here.
The table below lists units supported by {{convert}}. More complete lists are linked for each dimension. For a complete list of all dimensions, see full list of units.
{{Convert}} 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 displayed in column 3 of the following tables. These are accepted as input by {{convert}} as the second and third unnamed parameters:
{{convert|100|kg|lb}}
→ 100 kilograms (220 lb){{convert|100|lb|kg}}
→ 100 pounds (45 kg)The unit-codes should be treated as case-sensitive:
{{convert|100|Mm|mm}}
→ 100 megametres (1.0×1011 mm)The output of {{convert}} can display multiple converted units, if further unit-codes are specified after the second unnamed parameter (without the pipe separator). Typical combination output units are listed below in column 7.
{{convert|55|nmi|km mi}}
→ 55 nautical miles (102 km; 63 mi){{convert|1|oz|ozt g gr}}
→ 1 ounce (0.91 ozt; 28 g; 440 gr)
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 a lower-case f).

When using a slash (/
), a unit like kg/ha
is recognized as kilograms per hectare and will be converted in to other mass/area units. A unit in the numerator is not required.
{{convert|1000|kg/ha}}
→ 1,000 kilograms per hectare (890 lb/acre){{convert|350|/in2}}
→ 350 per square inch (54/cm2)Population density (inhabitants per square mile) can be converted using
{{convert|10|PD/sqmi|PD/km2}}
→ 10 inhabitants per square mile (3.9/km2)Vehicular fuel efficiency, commonly expressed in miles per gallonorlitres per 100 km can also be converted
{{convert|26|mpgUS|l/100km mpgimp}}
→ 26 miles per US gallon (9.0 l/100 km; 31 mpg‑imp)We have already discussed standard temperature conversions (°C, °F, K), as shown in these two examples:
{{convert|10|C}}
→ 10 °C (50 °F) (standard temperature conversion){{convert|10|-|15|C}}
→ 10–15 °C (50–59 °F) (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
.
Compare the following two examples with the two above:
{{convert|10|C-change}}
→ 10 °C (18 °F) increase in temperature{{convert|10|-|15|C-change}}
→ 10–15 °C (18–27 °F) warmer than normalTo produce multiple units in the output:
{{convert|10|C-change|F-change K-change}}
→ 10 °C (18 °F; 10 K) difference
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}}
→ 1 yard 2 feet 3 inches (1.60 m){{convert|2|ft|3|in|cm}}
→ 2 feet 3 inches (69 cm){{convert|1|lb|5|oz|g}}
→ 1 pound 5 ounces (600 g)
Available multiple-unit output options predefined, like ftin
and ydftin
. The full list is at § Output multiples.
{{convert|2|m|ftin}}
→ 2 metres (6 ft 7 in){{convert|2|m|ft in}}
→ 2 metres (6.6 ft; 79 in), using a space, returns the decimal pointDefault behavior, for comparison:
{{convert|2|m}}
→ 2 metres (6 ft 7 in)See also:
Using currency symbols in a $ per unit value, you can convert the per-unit:
{{convert|3.39|$/USgal|$/L}}
→ $3.39 per US gallon ($0.90/L){{convert|10000|€/ha|€/acre}}
→ €10,000 per hectare (€4,000/acre){{convert|10|¢/mi|¢/km}}
→ 10 cents per mile (6.2 ¢/km){{convert|1500|¥/lb|¥/kg}}
→ ¥1,500 per pound (¥3,300/kg)
You can also set the currency in both values using |$=€
:
{{convert|10|$/mi|$/km|$=€}}
→ €10 per mile (€6.2/km)It is not possible to convert the currency:
{{convert|10|$/lb|€/kg}}
→ $10 per pound ([convert: unit mismatch]) NSo, this result (mixed currencies) is not possible: $15 per mile (€8.6/km) N
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 vehicle range (P2073)ofCessna 208 Caravan (Q1056131):
{{convert|input=P2073|qid={{get QID|Cessna 208 Caravan}}|ftin|abbr=on}}
→ 1,500 mi (7,920,000 ft 0 in){{convert|input=P2073|qid=Q1056131|km|abbr=on}}
→ 1,500 mi (2,400 km){{convert|input=P2073|qid=Q1056131|km|abbr=on|disp=out}}
→ 2,400 km
Sometimes 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 diameter (P2386):
Note: this example uses |qid=Q1513315
(testing for South Pole Telescope (Q1513315))
{{convert|input=P2386|qual=Q613628|ft|abbr=on}}
→ 10.0 m (32.8 ft){{convert|input=P2386|qual=Q1395645|ft|abbr=on}}
→ 1 m (3.3 ft)Parameter
