Modèle:Transwiki guide

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

{{convert|2|km|mi}} → 2 kilometres (1.2 mi) (km entered, so converted into mile)
{{convert|7|mi|km}} → 7 miles (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 to 5 kilometres (1.2 to 3.1 mi)
{{convert|2|-|5|km|mi}} → 2–5 kilometres (1.2–3.1 mi)

Combined effect example:

{{convert|2|-|5|km|mi|2|abbr=on}} → 2–5 km (1.24–3.11 mi)
{{convert|2|and|5|km|mi|sigfig=3|abbr=off}} → 2 and 5 kilometres (1.24 and 3.11 miles)

Units to convert

Enter units to convert:

  • {{convert|1|lb|kg}} → 1 pound (0.45 kg)
SI units generally accept prefixes, like "m" for micro (10−3), and "M" for mega (106)
For "per" units, use "/" (slash): kg/ha
For three-unit units etc.: see Modèle:Cl

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

By default, the first quantity shows 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 kilograms)

To abbreviate both or neither:

  • {{convert|1|lb|kg|abbr=on}} → 1 lb (0.45 kg)
  • {{convert|1|lb|kg|abbr=off}} → 1 pound (0.45 kilograms)

When using scientific notation, the default is for the second (converted) quantity to be displayed using scientific notation:

  • {{convert|100|e6mi|e6km}} → 100 million miles (160×10^6 km)

To display thousands, millions, etc., while abbreviating both input and output units use |abbr=unit:

  • {{convert|100|e6mi|e6km|abbr=unit}} → 100 million mi (160 million km)

Convenience: Modèle:Tlf has |abbr=on by default

Template {{cvt}} is the same as Modèle:Tlf, except that it has |abbr=on as the default behaviour. In Modèle:Tlf, all other options are available. So:

{{cvt|1|lb|kg}}Modèle:Cvt

is equivalent to:

{{convert|1|lb|kg|abbr=on}}Modèle:Cvt

Adjective: a 10-mile distance

Use |adj=on to produce the adjectival (hyphenated) form:

  • A {{convert|10|mi|km|adj=on}} distance → A 10-mile (16 km) distance.

Default behaviour, for comparison:

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

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

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 Modèle:Tlf 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}} 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)
{{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}} 500 feet (15,000 cm) different output as with 0 (below)
{{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 Modèle:Frac 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)* Modèle:Nay

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)

Default behaviour, for comparison:

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

In a range, one can round each value individually to the default. Use |round=each:

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

Round to a multiple of a given fraction: Modèle:Frac inch

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

  • {{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)

Default behaviour uses decimal notation:

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

Rounding 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.

  2. Erreur de script : le module « DemoTemplate » n’existe pas.

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=:

Erreur de script : le module « DemoTemplate » n’existe pas.

or you set the precision positionally, relative to the decimal point (zero being at the decimal point):

Erreur de script : le module « DemoTemplate » n’existe pas.

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 tales 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-1Modèle:Nay 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 miles (6.66524 km) Modèle:Nay (precisions are mismatched)
  • {{convert|4.14159|mi|km|0|adj=ri0}} → 4 miles (7 km) Modèle:Aye

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) Modèle:Nay (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 kilometres (3.1 mi; 2.7 nmi)

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

Ranges of values

Modèle:For 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:
Modèle:Convert/doc/range separator list

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 ×, multiplication sign, or x, letter:

  • {{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:

Default behaviour, for comparison:

  • {{convert|1|ft|3|in|mm}} → 1 foot 3 inches (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 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}} → 10 miles (16,000 m)*

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

  • {{convert|10|mi|m|spell=on}}Erreur Lua dans Module:Convert à la ligne 402 : attempt to call upvalue 'speller' (a string value).

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

  • {{convert|10|mi|m|spell=In}} → 10 miles (16,000 m)*
  • {{convert|10|mi|m|spell=On}}Erreur Lua dans Module:Convert à la ligne 402 : attempt to call upvalue 'speller' (a string value).

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}}Erreur Lua dans Module:Convert à la ligne 402 : attempt to call upvalue 'speller' (a string value).

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

{{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 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)

Fractions: one-eighth of an imperial pint

The convert template also supports spelling out fractions.

  • {{convert|3+1/2|oz|g|spell=in}}3 12 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}}18 of an imperial pint (71 mL)*

Wrapping and line breaking

See Modèle:Section link

Numbers

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

Modèle:Sidebar metric prefixes (small) 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)

Modèle:Further information

Engineering notation: 7 × 106 m

In the unit: e6m

Engineering number notations like 7Modèle:Smallcaps6 (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 Modèle:Tlf, 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] Modèle:Nay Should be a number, not an expression (do not require a calculation)

Output with horizontal fraction bar in: Modèle:Sfrac 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}}[convert: invalid number] Modèle:Nay

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

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

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

  • {{convert|1234567|m|ft|comma=gaps}}1234567 metres (4050417 ft)

Default behaviour, for comparison:

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

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

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

Default behaviour, for comparison:

  • {{convert|1234|m|ft}} → 1,234 metres (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 metres [33 ft]
  • {{convert|10|m|ft|disp=comma}} → 10 metres, 33 ft
  • {{convert|10|m|ft|disp=or}} → 10 metres or 33 feet

Default behaviour, for comparison:

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

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

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

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

  • {{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|order=flip}} → 1,609.3 metres (1 mile)

Default behaviour, for comparison:

  • {{convert|1|mi|m}} → 1 mile (1,609.3 metres)

When converting to multiple units, the effect is:

  • {{convert|10|km|mi nmi|order=flip}} → 6.2137 miles; 5.3996 nautical miles (10 kilometres)
  • {{convert|10|km|nmi mi|order=flip}} → 5.3996 nautical miles; 6.2137 miles (10 kilometres)

Displaying parts of the result: 2 (1.5)

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

{{convert|2|cuyd|m3|disp=out|abbr=off}} 1.5 cubic metres Output value and unit

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 kilopascals [kPa] (0.29 psi)
  • A {{convert|2|kPa|psi|abbr=~|adj=on}} pressureModèle:Nowrap

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}} Modèle:Nowrap7001100000000000000</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

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

All units

Modèle:Selfref Modèle:Hatnote

'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: Expressing a change or difference in temperature

We have already discussed standard temperature conversions (°C, °F, K), as shown in these two examples:

  • Erreur de script : le module « DemoTemplate » n’existe pas. (standard temperature conversion)
  • Erreur de script : le module « DemoTemplate » n’existe pas. (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). 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:

  • Erreur de script : le module « DemoTemplate » n’existe pas. increase in temperature
  • Erreur de script : le module « DemoTemplate » n’existe pas. warmer than normal

To produce multiple units in the output:

  • Erreur de script : le module « DemoTemplate » n’existe pas. difference

Multiple units: 1 ft 5 in

In input

Base document Modèle:Slink 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 Modèle:Slink.

  • {{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

Default behaviour, for comparison:

  • {{convert|2|m}} → 2 metres (6 ft 7 in)

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 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: Modèle:!mxt Modèle:Nay

Using convert inside templates

For usage in template code, like infoboxes, Modèle:Tlf has these options:

Pre-formatting fraction 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 Modèle:Wikidata property link: Note: this example uses |qid=Q1056131 (testing for Modèle:Wikidata entity link)

  • {{convert|input=P2073|qid=Q1056131|ftin|abbr=on}} → P2073
  • {{convert|input=P2073|qid=Q1056131|km|abbr=on}} → P2073
  • {{convert|input=P2073|qid=Q1056131|km|abbr=on|disp=out}} → P2073
For example see template:Infobox Telescope.
