Template {{convert}} calculates measurements from one unit (you can enter) to another one, and then presents the results. For example:

{{convert|2|km|mi}} → 2 kilometres (1.2 mi)
{{convert|7|mi|km}} → 7 miles (11 km)

The available units are listed below. Units are case-sensitive always (kW, not KW and not kw). Multiple formatting and calculation options are listed below.

See also Help:Convert for more complete information

Contents

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

By default, the first value shows unit name, the second the symbol (or abbreviation). Use |abbr=on/off to change this behaviour:

{{convert|1|lb|kg}} → 1 pound (0.45 kg) (To compare; default: first value shows unit name)
{{convert|1|lb|kg|abbr=on}} → 1 lb (0.45 kg)
{{convert|1|lb|kg|abbr=off}} → 1 pound (0.45 kilograms)
  • |abbr=in toggles the default behaviour (|abbr=out):
{{convert|1|lb|kg|abbr=in}} → 1 lb (0.45 kilograms)

Adjective: a 10-mile distance

Use |adj=on to produce the adjective form. The difference:

{{convert|10|mi|km}} to go → 10 miles (16 km) to go. (To compare, default)
A {{convert|10|mi|km|adj=on}} distance → A 10-mile (16 km) distance. (Adjective form)

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

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.

Default rounding

By 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}} 123 feet (40 m)
{{convert|123|ft|m|0}} 123 feet (37 m)
{{convert|123|ft|m|1}} 123 feet (37.5 m)
{{convert|550|ft|m|0}} 550 feet (168 m) Approximate value is 167.64 m
{{convert|550|ft|m}} 550 feet (170 m) Rounds to 170, when approximate value is 167.64 m
{{convert|500|ft|m|0}} 500 feet (152 m) Approximate value is 152.4 m
{{convert|500|ft|m}} 500 feet (150 m) Rounds to 150, when approximate value is 152.4 m

Convert supports four types of rounding:

Round to a given precision: use |precision=

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 power of 110 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>:

  • To compare: {{convert|1200|ft|m}} → 1,200 feet (370 m)
  • {{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)

Setting |sigfig= is meaningless

  • {{convert|1200|ft|m|sigfig=0}} → 1,200 feet (370 m)

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

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)
To compare: {{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 × 656 × 9,843 ft)
{{convert|10 x 200 x 3000|m|ft|round=each}} → 10 by 200 by 3,000 metres (33 × 660 × 9,800 ft)

Round to a multiple of a given fraction: 2 316 inch

Specify the desired denominator using |frac=<some positive integer>. (Denominator is the below-the-slash number, for example the 3 in 13).

{{convert|5.56|cm|in|frac=16}} → 5.56 centimetres (2 316 in)
{{convert|8|cm|in|frac=4}} → 8 centimetres (3 14 in)

The fraction is reduced when possible:

{{convert|8|cm|in|frac=100}} → 8 centimetres (3 320 in)
{{convert|8|cm|in}} → 8 centimetres (3.150 in) (To compare)

Rounding the 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.

{{convert|10|C|F K}} → 10 °C (50 °F; 283 K)

Note

For a temperature difference, like to convert "A rise of 10 °C", use |C-change=10 &tc.
{{convert|10|C-change|F-change K-change}} → A rise of 10 °C (18 °F; 10 K)

Into multiple units: 10 °C (50 °F; 283 K)

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 a '+' separator.

Ranges of values

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:

Multiple dimensions: 6 m × 12 m (20 ft × 39 ft)

Use "by"
{{convert|6|by|12|ft|m}} → 6 by 12 feet (1.8 by 3.7 m)
Use "×" or ""x""
{{convert|6|x|12|m|ft}} → 6 by 12 metres (20 ft × 39 ft)

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)

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|mm}} → 1 foot 3 inches (380 mm) (to compare)
  • {{convert|1|ft|3|in|x|3|ft|5|in|mm}} → 1 foot 3 inches ([convert: unknown unit])

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}} → 1 metre (3.3 ft)—default
{{convert|1|m|ft|sp=us}} → 1 meter (3.3 ft)

Spell out numbers: ten miles

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 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)

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}} → ten miles (sixteen thousand meters)

Extra words: 4 planted acres

Incomplete section
{{convert|4|acre||adj=pre|planted}} → 4 planted acres (1.6 ha)

Extra adjective words: A 10-foot-long corridor

{{convert|4|ft|m|adj=mid|-long}} → 10-foot-long (3.0 m)

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}} → 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)
Exception

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

  • {{convert|100|foot|abbr=off}} → 100 foot (30 metres)

Extreme changes for grammatical structure: The 18-, 24- and 32-pounder (8, 11 and 15 kg) cannons

This example is from the article Fort McHenry:

The American defenders had 18-, 24- and 32-pounder (8, 11 and 15 kg) cannons.

You can't get this sentence structure as a direct result of using {{convert}} and its options. However, you can get the correctly converted numbers and the grammatical structure you want to use by using {{convert}} plus three stages of editing, previewing and saving versions of the text you wish to change.

Stage 1: Enter the input numbers and units in {{convert}} as usual (this stage is just to get the calculated output):
  • had {{convert|18 |, |24 |, |32 |lb |kg |0 }} cannons
Get the converted data below by clicking Preview or Save:
→ had 18, 24, 32 pounds (8, 11, 15 kg) cannons
Stage 2: Change the resulting text from a {{convert|...}} template result to plain code by adding subst: to the template name (short for "substitution") :
  • had {{subst:convert|18 |, |24 |, |32 |lb |kg |0 }} cannons
Double-check this by clicking Preview. The preview will show the converted numbers are still correct:
→ had 18, 24, 32 pounds (8, 11, 15 kg) cannons
Then click Save.
Stage 3: Click Edit at the top of the article again, and then go to the text in the editing window. You'll see that the text is there in plain code. The template {{convert|...}} itself will have disappeared. You can change the text as needed. The substituted text and plain code in the editing window in this example would be:
had 18,&nbsp;24,&nbsp;32 pounds (8,&nbsp;11,&nbsp;15&nbsp;kg) cannons
You can edit this text as usual to add the grammatical features you wish. In this example, editing the above text to:
  • had 18-,_24-_and_32-pounder (8,&nbsp;11_and_15&nbsp;kg) cannons
And then saving your edit will show the following result in the article text:
→ "had 18-, 24- and 32-pounder (8, 11 and 15 kg) cannons"

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:

  • 12 Gm (1.2×1010 m)
  • 12 µm (1.2×10−5 m)

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

  • {{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: 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}} → 7 million metres (23,000,000 ft)

The same is possible for the output unit:

{{convert|23,000,000|ft|e6m}} → 23,000,000 feet (7.0×10^6 m)

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.

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)

Input with fractions: 1 12 inches (38.1 mm)

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

{{convert|1/2|in|mm|1}}12 inch (12.7 mm)
{{convert|1⁄2|in|mm|1}}12 inch (12.7 mm)

With integers, use a + sign

{{convert|2+1⁄2|in|mm|1}}2 12 inches (63.5 mm)

When negative, use a hyphen - and repeat it:

{{convert|-2-1⁄2|in|mm|1}}−2 12 inches (−63.5 mm)
{{convert|2-1⁄2|in|mm|1}} → 2–12 inch (50.8–12.7 mm) Note: this is read as a range
{{convert|-2+1⁄2|in|mm|1}}[convert: invalid number] 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}}1/2 inch (12.7 mm)
  • {{convert|2+1//2|in|mm|1}}2 1/2 inches (63.5 mm)

Thousands separator: 1,000 mi and 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}} → 1,234,567 metres (4,050,417 ft)
  • {{convert|1,234,567|m|ft}} → 1,234,567 metres (4,050,417 ft)
  • {{convert|1 234 567|m|ft}}[convert: invalid number] Red XN

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}} → 1,234,567 metres (4,050,417 ft) (To compare, default)
  • {{convert|1234567|m|ft|comma=gaps}}1234567 metres (4050417 ft)

Setting |comma=5 or |comma=gaps5 will only add the separator when the number of digits is 5 or more:

  • {{convert|1234|m|ft}} → 1,234 metres (4,049 ft) (To compare, default)
  • {{convert|1234|m|ft|comma=5}} → 1234 metres (4049 ft)
  • {{convert|1234567|m|ft|comma=5}} → 1,234,567 metres (4,050,417 ft)
  • {{convert|1234|m|ft|comma=gaps5}}1234 metres (4049 ft)*
  • {{convert|1234567|m|ft|comma=gaps5}}1234567 metres (4050417 ft)*

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}} → 10 metres (33 ft)—( ) brackets are the default
{{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=or}} → 10 metres or 33 feet

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

{{convert|10|m|ft|disp=br}} → 10 metres
33 feet

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

{{convert|10|m|ft|disp=br()}} → 10 metres
(33 feet)

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

{{convert|10|m|ft|disp=x|_MyText_}} → 10 metres_MyText_33 ft—(To display spaces, use &nbsp;)

Flipping (reordering) the two measurements: 1,609.3 metres (1 mile)

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

{{convert|1|mi|m}} → 1 mile (1,609.3 metres) (To compare, default)
{{convert|1|mi|m|order=flip}} → 1,609.3 metres (1 mile)

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)

Displaying parts of the result: 2 (1.5)

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

Convert Output Description
{{convert|2|cuyd|m3}} 2 cubic yards (1.5 m3) Default, to compare
{{convert|2|cuyd|m3|abbr=values}} 2 (1.5) Input and output numbers
{{convert|2|cuyd|m3|disp=unit}} cubic yards Input unit
{{convert|2|cuyd|m3|disp=unit|adj=on}} cubic-yard Input unit, adjective (hyphenated)
{{convert|2|cuyd|cuyd|0|disp=out|abbr=off}} 2 cubic yards Input (workaround)
{{convert|2|cuyd|m3|abbr=~}} 2 cubic yards [cu yd] (1.5 m3) Input: both name and symbol
{{convert|2|cuyd|m3|disp=unit2}} m3 Output unit (symbol)
{{convert|2|cuyd|m3|disp=unit2|abbr=off}} cubic metres Output unit (name)
{{convert|2|cuyd|m3|disp=number}} 1.5 Output value
{{convert|2|cuyd|m3|disp=out}} 1.5 m3 Output value and unit
{{convert|2|cuyd|m3|disp=out|abbr=off}} 1.5 cubic metres Output value and unit

Display input name and symbol: 2 kilopascals [kPa]

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}} pressureA 2-kilopascal [kPa] (0.29 psi) 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()
100 kilometres
62 miles
100 kilometres
(62 miles)

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}} → 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:

  m ft
|disp=table 10 33
|disp=tablecen 20 66
|disp=<other> (default) 30 metres (98 ft)

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 15 34 52
B 15.5 51
C 16.0 52.5
D 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.

Units

Units are case-sensitive: 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.

The unit-code (column 3), is accepted as input by the {{convert}} template. These can be used as the second or third unnamed parameter. Some units have alternative codes; these are shown in brackets e.g. °F (F): either may be entered for Fahrenheit.

Column 7 lists standard combinations of multiple converted outputs. For example, {{convert|55|nmi|km mi}} produces "55 nautical miles (102 km; 63 mi)". Such a combination must be used as the third unnamed parameter.

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}} → 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)

In output

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 point
  • {{convert|2|m}} → 2 metres (6 ft 7 in)—the default
See also
  • {{hands}} a length used to measure horses.

'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}} → 1,000 kilograms per hectolitre (100 lb/imp gal)

Currency per unit: $/mi, $/km

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

  • {{convert|10|$/mi|$/km}} → $10 per mile ($6.2/km) Green tickY
You can set the unit in both values using |$=€:
  • {{convert|10|$/mi|$/km|$=€}} → €10 per mile (€6.2/km)

You can not convert the currency. This outcome combination is not possible: $15 per mile (€8.6/km)
