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

{{convert|2|km|mi}} → 2 கிலோமீட்டர்கள் (1.2 mi) (km entered, so converted into mile)

{{convert|7|mi|km}} → 7 மைல்கள் (11 km) (mi entered, so 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 முதல் 5 கிலோமீட்டர்கள் (1.2 முதல் 3.1 mi)

{{convert|2|-|5|km|mi}} → 2–5 கிலோமீட்டர்கள் (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 மற்றும் 5 கிலோமீட்டர்கள் (1.24 மற்றும் 3.11 மைல்கள்)

See Help:Convert for more detailed, technical information

Units to convert

See also: Complete list of units for {{Convert}}

Enter units to convert from into:

• {{convert|1|lb|kg}} → 1 pound (0.45 kg)

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

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

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

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

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 is the reverse behaviour to the default:

• {{convert|1|lb|kg|abbr=in}} → 1 lb (0.45 கிலோகிராம்கள்)

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 கிலோகிராம்கள்)

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 10-மைல் (16 km) distance.

Default behaviour, for comparison:

• {{convert|10|mi|km}} to go → 10 மைல்கள் (16 km) to go.

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

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

See Help:Convert § Rounding for a more mathematical description of the rounding options

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 {{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 அடிகள் (40 m)
{{convert|123|ft|m}}	123 அடிகள் (37 m)	same output as with 0 (below)
{{convert|123|ft|m|0}}	123 அடிகள் (37 m)
{{convert|123|ft|m|1}}	123 அடிகள் (37.5 m)
{{convert|123|ft|m|2}}	123 அடிகள் (37.49 m)	The more-exact value is 37.4904 m or so, which gets converted to 37 m if this parameter is not specified at all.
{{convert|500|ft|m|-1}}	500 அடிகள் (150 m)
{{convert|500|ft|m}}	500 அடிகள் (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 அடிகள் (152 m)
{{convert|500|ft|m|1}}	500 அடிகள் (152.4 m)
{{convert|500|ft|m|2}}	500 அடிகள் (152.40 m)	exact value is 152.4 m
{{convert|500|ft|cm|-3}}	500 அடிகள் (15,000 cm)
{{convert|500|ft|cm}}	500 அடிகள் (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 அடிகள் (15,240 cm)

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}} → 1,200 அடிகள் (365.8 m)
• {{convert|1200|ft|m|sigfig=3}} → 1,200 அடிகள் (366 m)
• {{convert|1200|ft|m|sigfig=2}} → 1,200 அடிகள் (370 m)
• {{convert|1200|ft|m|sigfig=1}} → 1,200 அடிகள் (400 m)

Default behaviour, for comparison:

• {{convert|1200|ft|m}} → 1,200 அடிகள் (370 m)

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

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

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 மீட்டர்கள் (33 அடி)
• {{convert|10|m|ft|round=5}} → 10 மீட்டர்கள் (35 அடி)

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

• {{convert|10|m|ft}} → 10 மீட்டர்கள் (33 அடி)
• {{convert|10|m|ft|round=25}} → 10 மீட்டர்கள் (25 அடி)

Default behaviour, for comparison:

• {{convert|10|m|ft|sigfig=4}} → 10 மீட்டர்கள் (32.81 அடி)

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 மீட்டர்கள் (33 அடி × 656 அடி × 9,843 அடி)
• {{convert|10 x 200 x 3000|m|ft|round=each}} → 10 by 200 by 3,000 மீட்டர்கள் (33 அடி × 660 அடி × 9,800 அடி)

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}} → 5.56 சென்டிமீட்டர்கள் (2+3⁄16 அங்)
• {{convert|8|cm|in|frac=4}} → 8 சென்டிமீட்டர்கள் (3+1⁄4 அங்)

The fraction is reduced when possible:

• {{convert|8|cm|in|frac=100}} → 8 சென்டிமீட்டர்கள் (3+3⁄20 அங்)

Default behaviour uses decimal notation:

• {{convert|5.56|cm|in}} → 5.56 சென்டிமீட்டர்கள் (2.19 அங்)

Rounding temperatures: °C, °F and K

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.

1. {{convert|10,000|C|F K}} → 10,000 °C (18,000 °F; 10,300 K)
2. {{convert|10,000.1|C|F K}} → 10,000.1 °C (18,032.2 °F; 10,273.2 K)
3. {{convert|-272|C|F K}} → −272 °C (−457.60 °F; 1.15 K)
4. {{convert|-272|C}} → −272 °C (−457.60 °F)
5. {{convert|100|C|F K}} → 100 °C (212 °F; 373 K)
6. {{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 மதிப்புறு இலக்கங்கள் 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, 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 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 there is no |adj=ri-1N 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}} → 4 மைல்கள் (6.66524 km) N (precisions are mismatched)
• {{convert|4.14159|mi|km|0|adj=ri0}} → 4 மைல்கள் (7 km) Y

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}} → 4 மைல்கள் (6 km) N (double rounding)

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 கிலோமீட்டர்கள் (3.1 mi; 2.7 nmi)

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

Ranges of values

a conversion of a difference குறித்து அறிய, காண்க #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}}

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

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

Use by:

• {{convert|6|by|12|ft|m}} → 6 கீழ் 12 அடிகள் (1.8 கீழ் 3.7 m)

Use ×, multiplication sign, or x, letter:

• {{convert|6|x|12|m|ft}} → 6 by 12 மீட்டர்கள் (20 அடி × 39 அடி)

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 அடி × 39 அடி)

Lists of values: 20, 40, or 60 miles

{{convert|20|,|40|, or|60|mi}} → 20, 40, அல்லது 60 மைல்கள் (32, 64, அல்லது 97 km)

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}} → 1 அடி 3 அங்குலங்கள் () N

Default behaviour, for comparison:

• {{convert|1|ft|3|in|mm}} → 1 அடி 3 அங்குலங்கள் (380 mm)

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 மீட்டர் (3.3 அடி)—default

{{convert|1|m|ft|sp=us}} → 1 மீட்டர் (3.3 அடி)

Spell out numbers: ten miles

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

• {{convert|10|mi|m|spell=in}} → பத்து மைல்கள் (16,000 m)

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

• {{convert|10|mi|m|spell=on}} → பத்து மைல்கள் (sixteen thousand மீட்டர்கள்)

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

• {{convert|10|mi|m|spell=In}} → பத்து மைல்கள் (16,000 m)
• {{convert|10|mi|m|spell=On}} → பத்து மைல்கள் (sixteen thousand மீட்டர்கள்)

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}} → பத்து மைல்கள் (sixteen thousand மீட்டர்கள்)

Inserted before units: 4 planted acres

• {{convert|4|acre||adj=pre|planted}} → 4 planted ஏக்கர்கள் (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 ஏக்கர்கள் (1.6 planted ha)
• {{convert|4|acre||disp=preunit|planted |reforested-}} → 4 planted ஏக்கர்கள் (1.6 reforested-ha)

After adjective unit: A 10-அடி-long corridor

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-அடி-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 மீட்டர் (3 அடி 3 அங்)
• {{convert|2|metre}} → 2 மீட்டர்கள் (6 அடி 7 அங்)
• {{convert|2|metre|abbr=on}} → 2 m (6 அடி 7 அங்)

Exception

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

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

Fractions: one-eighth of an imperial pint

The convert template also supports spelling out fractions.

• {{convert|3+1/2|oz|g|spell=in}} → மூன்று and a half அவுன்சுகள் (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)

Wrapping and line breaking

See Help:Convert § Wrapping and line breaking

Spelling out "thousands", "millions", etc.

Most unit codes accept a prefix of e3 (thousand) or e6 (million) or e9 (billion).

• {{convert|100|e6mi|e6km}} → 100 மில்லியன் மைல்கள் (160×10^⁶ km)
• {{convert|120|e6acre}} → 120 மில்லியன் ஏக்கர்கள் (490,000 km²)
• {{convert|120|e6acre|e3km2}} → 120 மில்லியன் ஏக்கர்கள் (490×10^³ km²)

To display both input and output in scientific notation, use |abbr=on

• {{convert|100|e6mi|e6km|abbr=on}} → 100×10^⁶ mi (160×10^⁶ km)

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 மில்லியன் mi (160 மில்லியன் km)
• {{convert|100|e6mi|e6km|abbr=off}} → 100 மில்லியன் மைல்கள் (160 மில்லியன் கிலோமீட்டர்கள்)

Numbers

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

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 அடி)
• mm: 12 mm (0.47 அங்)
• 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 அங் (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 notation can be entered as a "prefix" to the unit:

• {{convert|70|e6m}} → 70×10^⁶ m (230,000,000 அடி)

The same is possible for the output unit:

• {{convert|23,000,000|ft|e6m}} → 23,000,000 அடிகள் (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 அறிவியல் குறியீடு, 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)

Input with fractions: 1+1⁄2 அங்குலங்கள் (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}} → 1⁄2 அங்குலம் (12.7 mm)
• {{convert|1⁄2|in|mm|1}} → 1⁄2 அங்குலம் (12.7 mm)

With positive பின்னம்s (a positive integer and a fraction), use a + sign

• {{convert|2+1⁄2|in|mm|1}} → 2+1⁄2 அங்குலங்கள் (63.5 mm)

With negative mixed numbers, use a hyphen - and repeat it:

• {{convert|-2-1⁄2|in|mm|1}} → −2+1⁄2 அங்குலங்கள் (−63.5 mm)

Note that the following cases are not interpreted as mixed numbers:

• {{convert|2-1⁄2|in|mm|1}} → 2–1⁄2 அங்குலம் (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}} → N This is neither a mixed number nor a range, and mathematical expressions requiring calculations are not allowed here.

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 அங்குலம் (12.7 mm)
• {{convert|2+1//2|in|mm|1}} → 2+1/2 அங்குலங்கள் (63.5 mm)

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}} → 1,234,567 மீட்டர்கள் (4,050,417 அடி)
• {{convert|1,234,567|m|ft}} → 1,234,567 மீட்டர்கள் (4,050,417 அடி)
• {{convert|1 234 567|m|ft}} → N

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

• {{convert|1234567|m|ft|comma=off}} → 1234567 மீட்டர்கள் (4050417 அடி)

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

• {{convert|1234567|m|ft|comma=gaps}} → 1234567 மீட்டர்கள் (4050417 அடி)

Default behaviour, for comparison:

• {{convert|1234567|m|ft}} → 1,234,567 மீட்டர்கள் (4,050,417 அடி)

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

• {{convert|1234|m|ft|comma=5}} → 1234 மீட்டர்கள் (4049 அடி)
• {{convert|1234567|m|ft|comma=5}} → 1,234,567 மீட்டர்கள் (4,050,417 அடி)

Default behaviour, for comparison:

• {{convert|1234|m|ft}} → 1,234 மீட்டர்கள் (4,049 அடி)

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}} → 10 மீட்டர்கள் [33 அடி]
• {{convert|10|m|ft|disp=comma}} → 10 மீட்டர்கள், 33 அடி
• {{convert|10|m|ft|disp=or}} → 10 மீட்டர்கள் or 33 அடிகள்

Default behaviour, for comparison:

• {{convert|10|m|ft}} → 10 மீட்டர்கள் (33 அடி)

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

• {{convert|10|m|ft|disp=br}} → 10 மீட்டர்கள்
  33 அடிகள்

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

• {{convert|10|m|ft|disp=br()}} → 10 மீட்டர்கள்
  (33 அடிகள்)

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

• {{convert|10|m|ft|disp=x|_MyText_}} → 10 மீட்டர்கள்_MyText_33 அடி (To display spaces, use  )

Flipping (reordering) the two measurements: 1,609.3 மீட்டர்கள் (1 மைல்)

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

• {{convert|1|mi|m|order=flip}} → 1,609.3 மீட்டர்கள் (1 மைல்)

Default behaviour, for comparison:

• {{convert|1|mi|m}} → 1 மைல் (1,609.3 மீட்டர்கள்)

When converting to multiple units, the effect is:

• {{convert|10|km|mi nmi|order=flip}} → 6.2137 மைல்கள்; 5.3996 கடல் மைல்கள் (10 கிலோமீட்டர்கள்)
• {{convert|10|km|nmi mi|order=flip}} → 5.3996 கடல் மைல்கள்; 6.2137 மைல்கள் (10 கிலோமீட்டர்கள்)

Fixed ordering of output units: 212 °F (100 °C; 373 K)

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.

Displaying parts of the result: 2 (1.5)

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

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=~}} → 2 கிலோpascals [kPa] (0.29 psi)
• A {{convert|2|kPa|psi|abbr=~|adj=on}} pressure → A 2-கிலோpascal [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 கிலோமீட்டர்கள் 62 மைல்கள்	100 கிலோமீட்டர்கள் (62 மைல்கள்)

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 மீட்டர்கள் (98 அடி)

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 data-sort-value="7001100000000000000♠"></span>10 metres (33 ft)

showing: 10 மீட்டர்கள் (33 அடி).

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

	m	ft
A	15+3⁄4	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.

All units

See also: Convert/list of units

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

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 கிலோகிராம்கள் (220 lb)
• {{convert|100|lb|kg}} → 100 pounds (45 kg)

The unit-codes should be treated as case-sensitive:

• {{convert|100|Mm|mm}} → 100 மெகாமீட்டர்கள் (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 கடல் மைல்கள் (102 km; 63 mi)
• {{convert|1|oz|ozt g gr}} → 1 அவுன்சு (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).

'per' units: kg/hl, miles per gallon

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 கிலோகிராம்கள் per எக்டோலிட்டர் (100 lb/imp gal)

Population density (inhabitants per square mile) can be converted using

• {{convert|10|PD/sqmi|PD/sqkm}} → 10 inhabitants per square mile (3.9/km²)

Vehicular fuel efficiency, commonly expressed in miles per gallon or litres per 100 km can also be converted

• {{convert|26|mpgUS|l/100km mpgimp}} → 26 மைல்கள் per அமெரிக்க கலன் (9.0 l/100 km; 31 mpg_‑imp)

Units of difference: Expressing a change or difference in temperature

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 normal

To produce multiple units in the output:

• {{convert|10|C-change|F-change K-change}} → 10 °C (18 °F; 10 K) difference

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 யார்டு 2 அடிகள் 3 அங்குலங்கள் (1.60 m)
• {{convert|2|ft|3|in|cm}} → 2 அடிகள் 3 அங்குலங்கள் (69 cm)
• {{convert|1|lb|5|oz|g}} → 1 pound 5 அவுன்சுகள் (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 மீட்டர்கள் (6 அடி 7 அங்)
• {{convert|2|m|ft in}} → 2 மீட்டர்கள் (6.6 அடி; 79 அங்), using a space, returns the decimal point

Default behaviour, for comparison:

• {{convert|2|m}} → 2 மீட்டர்கள் (6 அடி 7 அங்)

See also:

• {{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}} → $10 per மைல் ($6.2/km)
• {{convert|1500|$/ozt|$/g}} → $1,500 per troy ounce ($48/g)

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

• {{convert|10|$/mi|$/km|$=€}} → €10 per மைல் (€6.2/km)

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

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 Cessna 208 Caravan (Q1056131))

• {{convert|input=P2073|qid=Q1056131|ftin|abbr=on}} → 1,500 mi (7,920,000 அடி 0 அங்)
• {{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

For example see template:Infobox Telescope.

Sometimes a property may have more than one value against in in Wikidata. You can use the |qual= parameter to specify which of the values you want to use.

Example for விட்டம் (P2386): Note: this example uses |qid=Q1513315 (testing for South Pole Telescope (Q1513315))

• primary mirror (Q613628): {{convert|input=P2386|qual=Q613628|ft|abbr=on}} → 10.0 m (32.8 அடி)
• secondary mirror (Q1395645): {{convert|input=P2386|qual=Q1395645|ft|abbr=on}} → 1 m (3.3 அடி)
