வார்ப்புரு:Convert

Template documentation[view] [edit] [history] [purge]

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 (வார்ப்புரு:Xt, 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, the second the symbols (= abbreviation). Use |abbr=on/off to change this behaviour:

{{convert|1|lb|kg}} → 1 pound (0.45 kg) (To compare; default: first value shows unit name)

{{convert|1|lb|kg|abbr=on}} → 1 lb (0.45 kg)

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

• |abbr=in toggles the default behaviour (|abbr=out):

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

Adjective: a 10-mile distance

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

{{convert|10|mi|km}} to go → 10 miles (16 km) to go. (To compare, default)

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

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

By definition, 100 ft equals 30,480 mm. In practical use, it is common to round the calculated metric number. With that, there are several possibilities.

Default rounding

By default, the conversion result will be rounded either to precision comparable to that of the input value (the number of digits after the decimal point—or the negative of the number of non-significant zeroes before the point—is increased by one if the conversion is a multiplication by a number between 0.02 and 0.2, remains the same if the factor is between 0.2 and 2, is decreased by 1 if it is between 2 and 20, and so on) or to two significant figures, whichever is more precise. An exception to this is rounding temperatures (see below).

Examples of rounding
Input	Displays as	Note
{{convert|123|ft|m|-1}}	123 feet (40 m)
{{convert|123|ft|m|0}}	123 feet (37 m)
{{convert|123|ft|m|1}}	123 feet (37.5 m)
{{convert|550|ft|m|0}}	550 feet (168 m)	Approximate value is 167.64 m
{{convert|550|ft|m}}	550 feet (170 m)	Rounds to 170, when approximate value is 167.64 m
{{convert|500|ft|m|0}}	500 feet (152 m)	Approximate value is 152.4 m
{{convert|500|ft|m}}	500 feet (150 m)	Rounds to 150, when approximate value is 152.4 m

Convert supports four types of rounding:

Round to a given precision: use |precision=

Specify the desired precision with the fourth unnamed parameter (or third unnamed parameter if the "convert to" parameter is omitted; or fifth unnamed parameter if a range is specified; or fourth unnamed parameter again if a range is specified and the "convert to" parameter is omitted; needs to be replaced with a "precision" named parameter). The conversion is rounded off to the nearest power of 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: use |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)

Rounding the temperatures °C, °F and K

In temperatures, the conversion will be rounded either to precision comparable to that of the input value or to that which would give three significant figures when expressed in kelvins, whichever is more precise.

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

Note

For a temperature difference, like to convert "A rise of 10 °C", use |C-change=10 &tc.

{{convert|10|C-change|F-change K-change}} → A rise of 10 °C (18 °F; 10 K)

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

Separate the multiple output units by a space:

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

{{convert|5|km|mi nmi}} → 5 kilometres (3.1 mi; 2.7 nmi)

Ranges of values

A range: 6 to 17 kg (13 to 37 lb)

Range indicators are entered as the second parameter (between the values). Range separators can be:
வார்ப்புரு: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 "×" 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}} → பத்து miles (16,000 m)

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

{{convert|10|mi|m|spell=on}} → பத்து miles (sixteen thousand metres)

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

{{convert|10|mi|m|spell=In}} → பத்து miles (16,000 m)

{{convert|10|mi|m|spell=On}} → பத்து 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}} → பத்து 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)

Grammatical construction: The 18-, 24- and 32-pounder (8, 11 and 15 kg) cannons

This example is from article Fort McHenry:

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

This formatted result is not possible straightforward by using {{convert}}. However, it can be made in three steps.

Step 1: Enter the input numbers and units in {{convert}} just to get the calculated output:

• had {{convert|18 |, |24 |, |32 |lb |kg |0 }} cannons

→ had 18, 24, 32 pounds (8, 11, 15 kg) cannons

The core conversion should look good now. You can save this (or preview).

Step 2: We need the resulting text in plain code in the page, not as a {{convert|...}} template.

For this, add subst: to the template name (for 'substitute') :

• had {{வார்ப்புரு:Purpleconvert|18 |, |24 |, |32 |lb |kg |0 }} cannons

As a check: the preview result should show the conversion correct, with the numbers still right.

Now save this.

→ had 18, 24, 32 pounds (8, 11, 15 kg) cannons

Step 3: When opening the edit screen again, you'll see that the text is there in code. The template {{convert|...}} itself has disappeared. You can change the text as needed. The edit screen text is:

had 18, 24, 32 pounds (8, 11, 15 kg) cannons

You can edit this text to add the grammar:

• had 18-,_24-_and_32-pounder (8, 11_and_15 kg) cannons

After saving your edit, it shows:

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

Numbers

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

வார்ப்புரு: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)

Engineering notation: 7 × 10⁶ m

In the unit: e6m

Engineering number notations like 7E6 (for 7 × 10⁶) can be entered as a "prefix" to the unit:

{{convert|7|e6m}} → 7 million metres (23,000,000 ft)

The same is possible for the output unit:

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

Any standard unit (not a combination, multiple, or built-in unit) can have such a prefix:

e3 (thousand), e6 (million), e9 (billion), e12 (trillion), e15 (quadrillion).

Scientific notation: 1.23×10⁻¹⁴

In scientific notation, a number is written like 1.23×10⁻¹⁴.

With {{convert}}, the input can be in e-notation such as 12.3e4. This value is displayed as a power of ten, and the output is displayed in scientific notation, except that an output value satisfying 0.01 <= v < 1000 is shown as a normal number. In addition, if the output value is 1000 and sigfig=4 is used, the value is displayed as a normal number.

• {{convert|12.3e-15|atm|atm|abbr=on}} → 12.3×10⁻¹⁵ atm (1.23×10⁻¹⁴ atm)
• {{convert|0.00000005|atm|atm|abbr=on}} → 0.00000005 atm (5.0×10⁻⁸ atm)

Input with fractions: 1 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}} → வார்ப்புரு:Nay Should be a number, not an expression (do not require a calculation)

Output with horizontal fraction bar in: 1/2 inch

Using a double slash (//) returns a horizontal bar fraction:

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

Thousands separator: 1,000 mi and 1000 mi

In input, a comma for thousands separator is accepted. A gap (space) is not. In output, by default, the thousand separator is the comma:

• {{convert|1,234,567|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}} → வார்ப்புரு:Nay

Set |comma=off to remove the separator:

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

Use |comma=gaps to set digit grouping by gap (<space>) in larger numbers (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:

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

Display input name and symbol: 2 kilopascals [kPa]

Setting |abbr=~ returns both name and symbol of the first (input) unit:

{{convert|2|kPa|psi|abbr=~}} → 2 kilopascals [kPa] (0.29 psi)

A {{convert|2|kPa|psi|abbr=~|adj=on}} pressure → A 2-kilopascal [kPa] (0.29 psi) pressure

Table options

For the wikitable structure, there are three options: add a line-break, split the result over columns and make the table sortable.

Enforced line break

|disp=br adds a line-break and omits brackets.

|disp=br()</nowiki> adds a lnie-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 both |disp=table |sortable=on to produce table columns (pipe symbols), with sortable table column. As of January 2013, only the first (lefthand) column will sort (improvements pending).

{{convert|10|m|ft|disp=table|sortable=on}} →

style="text-align:right;" data-sort-value="7001100000000000000"|10 |style="text-align:right;" data-sort-value="7001100000000000000"|33

This shows the hidden numerical sortkey:

'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)
