Skabelon:Convert
 | Denne skabelon bruges på ca. 420 sider, og derfor vil ændringer blive bemærket af mange. Vær venlig at afprøve enhver ændring i skabelonens /sandkasse eller /test-undersider, eller i din egen brugerunderside. Du bør også overveje at diskutere ændringer på diskussionssiden før du implementerer dem. |
 | Denne skabelon bruger Lua: |
Skabelon {{convert}} omregner fra en måleenhed til en anden, og viser resultatet efter et valgt format. For eksempel:
{{convert|2|km|mi}}→ 2 kilometer (1,2 mi){{convert|7|mi|km}}→ 7 miles (11 km)
Tal kan afrundes, enheder kan forkortes:
{{convert|2|km|mi|2|abbr=on}}→ 2 km (1,24 mi){{convert|7|mi|km|2|abbr=on}}→ 7 mi (11,27 km)
Et interval kan angives med |to|... eller |-|...:
{{convert|2|to|5|km|mi}}→ 2 til 5 kilometer (1,2 til 3,1 mi){{convert|2|-|5|km|mi}}→ 2–5 kilometer (1,2–3,1 mi)
Kombineret eksempel:
{{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 og 5 kilometer (1,24 og 3,11 miles)
Vær opmærksom på at komma bruges til decimaltal. Hvis tal angives med punktum i stedet, vises en asterisk (*) eller fejlmeddelelse til slut og artiklen kommer i Kategori:Sider med fejl eller advarsel ved enhedskonvertering. Undgå derfor også punktum som tusindadskiller, da det ikke altid kan fortolkes korrekt.
Konverter enheder
Angiv enhederne, der skal konverteres fra til:
{{convert|1|lb|kg}}→ 1 pound (0,45 kg)
- SI-enhederne kan som regel bruge præfiks, fx "m" for milli (10−3) og "M" for mega (106)
- For "per" enhed, brug "/" (skråstreg): kg/ha
Enhedsnavn eller symbol (forkortelse): 1 pound eller 1 lb?
Som standard, vises første mængde med enhedsnavn, mens det andet vises med symbol (eller forkortelse):
{{convert|1|lb|kg}}→ 1 pound (0,45 kg)
Anvendes |abbr=in er det omvendt i forhold til standard:
{{convert|1|lb|kg|abbr=in}}→ 1 lb (0,45 kilogram)
For at forkorte begge eller ingen:
{{convert|1|lb|kg|abbr=on}}→ 1 lb (0,45 kg){{convert|1|lb|kg|abbr=off}}→ 1 pound (0,45 kilogram)
Afrunding: 100 ft er 30 m eller 30,5 m eller 30,48 m?
Per definition er 100 ft lig 30,48 m. I praksis afrundes resultatet sædvanligvis.
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 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) | exact value is 37.4904 m |
{{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:
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 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 behaviour, 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)*
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 meter (33 ft){{convert|10|m|ft|round=5}}→ 10 meter (35 ft)
Similar: using |round=25 rounds the outcome to a multiple of 25.
{{convert|10|m|ft}}→ 10 meter (33 ft){{convert|10|m|ft|round=25}}→ 10 meter (25 ft)
Default behaviour, for comparison:
{{convert|10|m|ft|sigfig=4}}→ 10 meter (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 gange 200 gange 3.000 meter (33 ft × 656 ft × 9.843 ft){{convert|10 x 200 x 3000|m|ft|round=each}}→ 10 gange 200 gange 3.000 meter (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 centimeter (2 3⁄16 in){{convert|8|cm|in|frac=4}}→ 8 centimeter (3 1⁄4 in)
The fraction is reduced when possible:
{{convert|8|cm|in|frac=100}}→ 8 centimeter (3 3⁄20 in)
Default behaviour uses decimal notation:
{{convert|5,56|cm|in}}→ 5,56 centimeter (2,19 in)
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.
{{convert|10000|C|F K}}→ 10.000 °C (18.000 °F; 10.300 K){{convert|10000,1|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, 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-1
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)(precisions are mismatched)
{{convert|4,14159|mi|km|0|adj=ri0}}→ 4 miles (7 km)
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 miles (6 km)
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 kilometer (3,1 mi; 2,7 nmi)
If the output unit names contain spaces, use + as the separator.

Multiple dimensions: 6 m × 12 m (20 ft × 39 ft)
Use by:
{{convert|6|by|12|ft|m}}→ 6 gange 12 feet (1,8 gange 3,7 m)
Use ×, multiplication sign, or x, letter:
{{convert|6|x|12|m|ft}}→ 6 gange 12 meter (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|x|3|ft|5|in|mm}}→ 1 foot 3 inchs ([convert: ukendt enhed])*
Default behaviour, for comparison:
{{convert|1|ft|3|in|mm}}→ 1 foot 3 inchs (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 meter (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}}→ ti miles (16.000 m)
To spell out both in and out values, use |spell=on:
{{convert|10|mi|m|spell=on}}→ ti miles (seksten tusind meter)
To make first letter a capital, use |spell=In, |spell=On
{{convert|10|mi|m|spell=In}}→ Ti miles (16.000 m){{convert|10|mi|m|spell=On}}→ Ti miles (seksten tusind meter)
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}}→ ti miles (seksten tusind meter)
Inserted before units: 4 planted acres
{{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)
After adjective unit: A 10-foot-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-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 meter (3 ft 3 in){{convert|2|metre}}→ 2 meter (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 feet (30 meter)
Fractions: one-eighth of an imperial pint
The convert template also supports spelling out fractions.
{{convert|3+1/2|oz|g|spell=in}}→ tre 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)
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 million miles (160×106 km){{convert|120|e6acre}}→ 120 million acres (490.000 km2){{convert|120|e6acre|e3km2}}→ 120 million acres (490×103 km2)
To display both input and output in scientific notation, use |abbr=on
{{convert|100|e6mi|e6km|abbr=on}}→ 100×106 mi (160×106 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 million mi (160 million km){{convert|100|e6mi|e6km|abbr=off}}→ 100 million miles (160 million kilometer)
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 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)
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 inchs (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 positive mixed numbers (a positive integer and a fraction), use a + sign
{{convert|2+1⁄2|in|mm|1}}→ 2 1⁄2 inchs (63,5 mm)
With negative mixed numbers, use a hyphen - and repeat it:
{{convert|-2-1⁄2|in|mm|1}}→ −2 1⁄2 inchs (−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: ugyldigt tal]
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 inchs (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 meter (4.050.417 ft){{convert|1,234,567|m|ft}}→ 1.234.567 meter (4.050.417 ft)*{{convert|1 234 567|m|ft}}→ [convert: ugyldigt tal]
Set |comma=off to remove the separator from the output:
{{convert|1234567|m|ft|comma=off}}→ 1234567 meter (4050417 ft)
Use |comma=gaps to use digit grouping by gap (thin space) as a thousands separator:
{{convert|1234567|m|ft|comma=gaps}}→ 1234567 meter (4050417 ft)
Default behaviour, for comparison:
{{convert|1234567|m|ft}}→ 1.234.567 meter (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 meter (4049 ft){{convert|1234567|m|ft|comma=5}}→ 1.234.567 meter (4.050.417 ft)
Default behaviour, for comparison:
{{convert|1234|m|ft}}→ 1.234 meter (4.049 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|disp=sqbr}}→ 10 meter [33 ft]{{convert|10|m|ft|disp=comma}}→ 10 meter, 33 ft{{convert|10|m|ft|disp=or}}→ 10 meter eller 33 feet
Default behaviour, for comparison:
{{convert|10|m|ft}}→ 10 meter (33 ft)
Setting |disp=br will force a new line (<br/>)
{{convert|10|m|ft|disp=br}}→ 10 meter
33 feet
Also |disp=br() will force a new line, and keep the brackets (useful in tables):
{{convert|10|m|ft|disp=br()}}→ 10 meter
(33 feet)
Setting |disp=x|… allows any text as separator:
{{convert|10|m|ft|disp=x|_MyText_}}→ 10 meter_MyText_33 ft (To display spaces, use )
Flipping (reordering) the two measurements: 1.609,3 meter (1 mile)
Setting |order=flip will flip (swap) the two measurements:
{{convert|1|mi|m|order=flip}}→ 1.609,3 meter (1 mile)
Default behaviour, for comparison:
{{convert|1|mi|m}}→ 1 mile (1.609,3 meter)
When converting to multiple units, the effect is:
{{convert|10|km|mi nmi|order=flip}}→ 6,2137 miles; 5,3996 sømil (10 kilometer){{convert|10|km|nmi mi|order=flip}}→ 5,3996 sømil; 6,2137 miles (10 kilometer)
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)

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 kilometer 62 miles |
100 kilometer (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=table10 33 |disp=tablecen20 66 |disp=<other>(default)30 meter (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 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.

All units
- See also: Convert/list of units
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 kilogram (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 megameter (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 sømil (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 kilogram per hektolitre (100 lb/imp gal)
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 yard 2 feet 3 inchs (1,60 m){{convert|2|ft|3|in|cm}}→ 2 feet 3 inchs (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 meter (6 ft 7 in){{convert|2|m|ft in}}→ 2 meter (6,6 ft; 79 in), using a space, returns the decimal point
Default behaviour, for comparison:
{{convert|2|m}}→ 2 meter (6 ft 7 in)
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 ($6,2/km)
You can set the currency in both values using |$=€:
{{convert|10|$/mi|$/km|$=€}}→ €10 per mile (€6,2/km)
It is not possible to convert the currency. So, this result (mixed currencies) is not possible: $15 per mile (€8,6/km)
