Template:Convert/doc

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

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

By default, the first value shows unit name spelled out, 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)

This option does not work with |abbr=on.

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 {{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}}	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 ¹⁄₁₀ 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 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)

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 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)

{{convert|8|cm|in}} → 8 centimetres (3.150 in) (To compare)

In temperatures: rounding °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}} → 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|-300|C|F K}} → −300 °C (−508.0 °F; −26.9 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 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, 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 into five significant output digits because of the two numbers 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.

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

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:

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 ()

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, 24, 32 pounds (8, 11, 15 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, 11_and_15 kg) cannons

And then save your edit will show the following result in the article text:

→ "had 18-, 24- and 32-pounder (8, 11 and 15 kg) cannons"

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:

• 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)

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}} → 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. 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 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}} → 1⁄2 inch (12.7 mm)

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

With integers, use a + sign

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

When negative, use a hyphen - and repeat it:

{{convert|-2-1⁄2|in|mm|1}} → −2 1⁄2 inches (−63.5 mm)

{{convert|2-1⁄2|in|mm|1}} → 2–1⁄2 inch (50.8–12.7 mm) Note: this is read as a range

{{convert|-2+1⁄2|in|mm|1}} → 13pxN 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 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 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}} → 13pxN

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  )

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:

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}} pressure → A 2-kilopascal [kPa] (0.29 psi) pressure

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 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.

See also: complete Convert/list of 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 "100 kilograms (220 lb)" and {{convert|100|lb|kg}} produces "100 pounds (45 kg)"

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 "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 | separator). Typical combination output units are listed below in column 7. For example, {{convert|55|nmi|km mi}} produces "55 nautical miles (102 km; 63 mi)", and {{convert|1|oz|ozt g gr}} produces "1 ounce (0.91 ozt; 28 g; 440 gr)".

'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)

Units of difference

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}} → 10 °C (50 °F) -- regular temperature

{{convert|10|C-change}} → 10 °C (18 °F) -- difference (e.g., "The temperature changed from 30 into 40 °C")

{{convert|10-15|C}} → 10–15 °C (50–59 °F) -- 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 10 °C (18 °F; 10 K)

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

• {{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 mile ($6.2/km) 13pxY

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)
