Šablon:Convert/dok

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

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

{{convert|7|mi|km}} → (mi entered, so converted into km)

Numbers can be rounded, units can be abbreviated into symbols:

{{convert|2|km|mi|2|abbr=on}} →

{{convert|7|mi|km|2|abbr=on}} →

Value ranges can be entered using |to|... or |-|...:

{{convert|2|to|5|km|mi}} →

{{convert|2|-|5|km|mi}} →

Combined effect example:

{{convert|2|-|5|km|mi|2|abbr=on}} →

{{convert|2|and|5|km|mi|sigfig=3|abbr=off}} →

Units to convert

Enter units to convert from into:

• {{convert|1|lb|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 Kategorija: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}} →

Using |abbr=in is the reverse behaviour to the default:

• {{convert|1|lb|kg|abbr=in}} →

To abbreviate both or neither:

• {{convert|1|lb|kg|abbr=on}} →
• {{convert|1|lb|kg|abbr=off}} →

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}} →

is equivalent to:

{{convert|1|lb|kg|abbr=on}} →

Adjective: a 10-mile distance

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

• A {{convert|10|mi|km|adj=on}} distance → A distance.

Default behaviour, for comparison:

• {{convert|10|mi|km}} to go → 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?

By definition, 100 ft equals . 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}}
{{convert|123|ft|m}}		same output as with 0 (below)
{{convert|123|ft|m|0}}
{{convert|123|ft|m|1}}
{{convert|123|ft|m|2}}		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}}
{{convert|500|ft|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}}
{{convert|500|ft|m|1}}
{{convert|500|ft|m|2}}		exact value is 152.4 m
{{convert|500|ft|cm|-3}}
{{convert|500|ft|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}}

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}} →
• {{convert|1200|ft|m|sigfig=3}} →
• {{convert|1200|ft|m|sigfig=2}} →
• {{convert|1200|ft|m|sigfig=1}} →

Default behaviour, for comparison:

• {{convert|1200|ft|m}} →

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

• {{convert|1200|ft|m|sigfig=0}} → 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}} →
• {{convert|10|m|ft|round=5}} →

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

• {{convert|10|m|ft}} →
• {{convert|10|m|ft|round=25}} →

Default behaviour, for comparison:

• {{convert|10|m|ft|sigfig=4}} →

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

• {{convert|10 x 200 x 3000|m|ft}} →
• {{convert|10 x 200 x 3000|m|ft|round=each}} →

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}} →
• {{convert|8|cm|in|frac=4}} →

The fraction is reduced when possible:

• {{convert|8|cm|in|frac=100}} →

Default behaviour uses decimal notation:

• {{convert|5.56|cm|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.

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 , 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=:

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

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}} → N (precisions are mismatched)
• {{convert|4.14159|mi|km|0|adj=ri0}} → D

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}} → N (double rounding)

Into multiple units:

Separate the multiple output units by a space:

• {{convert|10|C|F K}} →
• {{convert|5|km|mi nmi}} →

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

• For multiple-unit options like 1 ft 5 in, see and .

Ranges of values

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:
Šablon:Convert/doc/range separator list

Multiple dimensions:

Use by:

• {{convert|6|by|12|ft|m}} →

Use ×, multiplication sign, or x, letter:

• {{convert|6|x|12|m|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}} →

Lists of values: 20, 40, or 60 miles

{{convert|20|,|40|, or|60|mi}} →

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}} → N

Default behaviour, for comparison:

• {{convert|1|ft|3|in|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}} → —default

{{convert|1|m|ft|sp=us}} →

Spell out numbers: ten miles

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

• {{convert|10|mi|m|spell=in}} →

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

• {{convert|10|mi|m|spell=on}} →

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

• {{convert|10|mi|m|spell=In}} →
• {{convert|10|mi|m|spell=On}} →

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}} →

Inserted before units: 4 planted acres

• {{convert|4|acre||adj=pre|planted}} →

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 }} →
• {{convert|4|acre||disp=preunit|planted |reforested-}} →

After adjective unit: A 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}} →

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}} →
• {{convert|2|metre}} →
• {{convert|2|metre|abbr=on}} →

Exception

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

• {{convert|100|foot|abbr=off}} →

Fractions: one-eighth of an imperial pint

The convert template also supports spelling out fractions.

• {{convert|3+1/2|oz|g|spell=in}} →

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}} →

Wrapping and line breaking

See

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

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

• {{convert|100|e6mi|e6km}} →
• {{convert|120|e6acre}} →
• {{convert|120|e6acre|e3km2}} →

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

• {{convert|100|e6mi|e6km|abbr=on}} →

To spell out "thousands", "millions", etc., |abbr=unit abbreviates the unit; |abbr=off displays both full unit names.

• {{convert|100|e6mi|e6km|abbr=unit}} →
• {{convert|100|e6mi|e6km|abbr=off}} →

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:

The prefix can be added before the SI unit (here: unit m for meter):

• {{convert|12|Gm|mi|abbr=on}} →
• Mm:
• km:
• mm:
• μm:
• um: (letter "u" can be used for "μ" here)

The prefix can be used in the output unit:

• {{convert|12000|mi|Mm|abbr=on}} →
• {{convert|12|in|μm|abbr=on}} →

As an exception, the non-SI unit "inch" can have the "μ" prefix too)

• {{convert|12|μm|μin|abbr=on}} →

Engineering notation: 7 × 10⁶ m

In the unit: e6m

Engineering notation can be entered as a "prefix" to the unit:

• {{convert|70|e6m}} →

The same is possible for the output unit:

• {{convert|23,000,000|ft|e6m}} →

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 . 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}} →
• {{convert|0.00000005|atm|atm|abbr=on}} →

Input with fractions:

The number to convert can be written in fractions. Both / (keyboard slash) and ⁄ (fraction slash) are accepted:

• {{convert|1/2|in|mm|1}} →
• {{convert|1⁄2|in|mm|1}} →

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

• {{convert|2+1⁄2|in|mm|1}} →

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

• {{convert|-2-1⁄2|in|mm|1}} →

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

• {{convert|2-1⁄2|in|mm|1}} → . 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:  inch

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

• {{convert|1//2|in|mm|1}} →
• {{convert|2+1//2|in|mm|1}} →

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}} →
• {{convert|1,234,567|m|ft}} →
• {{convert|1 234 567|m|ft}} → N

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

• {{convert|1234567|m|ft|comma=off}} →

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

• {{convert|1234567|m|ft|comma=gaps}} →

Default behaviour, for comparison:

• {{convert|1234567|m|ft}} →

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

• {{convert|1234|m|ft|comma=5}} →
• {{convert|1234567|m|ft|comma=5}} →

Default behaviour, for comparison:

• {{convert|1234|m|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}} →
• {{convert|10|m|ft|disp=comma}} →
• {{convert|10|m|ft|disp=or}} →

Default behaviour, for comparison:

• {{convert|10|m|ft}} →

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

• {{convert|10|m|ft|disp=br}} →

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

• {{convert|10|m|ft|disp=br()}} →

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

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

Flipping (reordering) the two measurements:

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

• {{convert|1|mi|m|order=flip}} →

Default behaviour, for comparison:

• {{convert|1|mi|m}} →

When converting to multiple units, the effect is:

• {{convert|10|km|mi nmi|order=flip}} →
• {{convert|10|km|nmi mi|order=flip}} →

Fixed ordering of output units:

Setting |order=out shows the output-units as ordered; the input unit is skipped:

• {{convert|100|C|F C K|abbr=on|order=out}} →
• {{convert|200|PS|kW hp|0|abbr=on|order=out}} →

See also: § Displaying parts of the output.

Displaying parts of the result:

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

Convert	Output	Returns
{{convert|2|cuyd|m3}}		Regular output (for comparison)
{{convert|2|cuyd|m3|abbr=values}}		Input and output numbers
{{convert|2|cuyd|m3|disp=unit}}		Input unit
{{convert|2|cuyd|m3|disp=unit|adj=on}}		Input unit, adjective (hyphenated)
{{convert|2|cuyd|cuyd|disp=out}}		Input (workaround. Note repetition of unit in input)
{{convert|2|cuyd|m3|abbr=~}}		Input: both name and symbol
{{convert|2|cuyd|m3|disp=unit2}}		Output unit (symbol)
{{convert|2|cuyd|m3|disp=unit2|abbr=off}}		Output unit (name)
{{convert|2|cuyd|m3|disp=number}}		Output value
{{convert|2|cuyd|m3|disp=out}}		Output value and unit name
{{convert|2|cuyd|m3|disp=out|abbr=off}}		Output value and unit symbol

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=~}} →
• A {{convert|2|kPa|psi|abbr=~|adj=on}} pressure → A 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()

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}} →

|disp=tablecen does the same, and also centers the text:

{{convert|20|m|ft|disp=tablecen}} →

The units are added as a column header:

	m	ft
|disp=table
|disp=tablecen
|disp=<other> (default)

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" class="sortkey">7001100000000000000♠</span>10 metres (33 ft)

showing: .

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

	m	ft
A
B
C
D

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

The conversion factors and physical constants are sourced here.

All 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 "" and {{convert|100|lb|kg}} produces ""

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 "".

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 "", and {{convert|1|oz|ozt g gr}} produces "".

'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}} →

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

• {{convert|10|PD/sqmi|PD/sqkm}} →

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

• {{convert|26|mpgUS|l/100km mpgimp}} →

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:

• (standard temperature conversion)
• (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:

• increase in temperature
• warmer than normal

To produce multiple units in the output:

• difference

Multiple units: 1 ft 5 in

In input

Base document 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}} →
• {{convert|2|ft|3|in|cm}} →
• {{convert|1|lb|5|oz|g}} →

In output

Available multiple-unit output options predefined, like ftin and ydftin. The full list is at .

• {{convert|2|m|ftin}} →
• {{convert|2|m|ft in}} → , using a space, returns the decimal point

Default behaviour, for comparison:

• {{convert|2|m}} →

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}} →
• {{convert|1500|$/ozt|$/g}} →

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

• {{convert|10|$/mi|$/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}} →

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 [ (Q1056131)])

• {{convert|input=P2073|qid=Q1056131|ftin|abbr=on}} →
• {{convert|input=P2073|qid=Q1056131|km|abbr=on}} →
• {{convert|input=P2073|qid=Q1056131|km|abbr=on|disp=out}} →

For example see template:Infobox Telescope.

Parametri šablona

Ovaj šablon preferira formatiranje parametara u jednom redu.

Parametar		Opis	Vrsta	Status
Value	1	The value to convert.	broj	obavezno
From unit	2	The unit for the provided value. Primer km	kratak tekst	obavezno
To units	3	The units to convert into. Separate units by a space for multiple outputs. In an output unit, use + for a multiplication space. Primer mi nmi	tekst	predloženo
Precision or suffix	4	Significant digits after decimal dot or, if negative, exponent of ten.	broj	neobavezno
Link units	lk	Indication of what units to apply wikilinks to. Use “on” for all, “in” for the input unit, “out” for the output units, or “off” for none of the units. Podrazumevano off Primer on	tekst	neobavezno
Abbreviation	abbr	Display for the units: “on” to display all units using their unit symbols, “off” to display all units in full words, “in” to display the unit symbol for the input unit, “out” to display the unit symbols for the output units, “unit” to display unit symbols for both input and output units when using scientific notation, “values” for no units at all (neither unit symbols nor full words of units). Podrazumevano out Primer on, unit, in, out, off	tekst	predloženo
Spelling	sp	Spelling of units. Use “us” to display unit names using U.S. spelling. Primer us	tekst	neobavezno
Adjective	adj	Whether to use adjectival form. Use “on” for singular unit name appended by a hyphen, “mid” to put conversion at end, or “off” (default) for no adjectival form. Podrazumevano off Primer on	uslovni izraz	neobavezno
Conversion	disp	Display conversion result: “or”: after ‘or’, “x”: with custom prefix and suffix, “b”: in parentheses, “table”/“tablecen”, “output only”: alone, “output number only”: alone and without unit, “unit”: not at all but input unit; if the value is a number it is used as precision. Primer b	tekst	zastarelo
Ordering	order	“flip” returns converted value first, input value second. Primer flip	tekst	neobavezno
Significant figures	sigfig	Indicates the number of significant figures to be used in rounding.	broj	neobavezno
Rounding output	round	The type of rounding. “5” rounds the output number to nearest multiple of 5, “25” to nearest multiple of 25, “each” rounds each number in a range.	broj	neobavezno
Thousands separator	comma	Sets or suppresses the use of thousands separators in the numbers. “off”: no separator; “gaps”: use space instead of comma as thousands separator; “5” and “gaps5”: only add thousands separator when the integral part of the number uses 5 positions or more (10,000 or more; if using comma as thousands separator, 1234 would produce '1234', 12345 would produce '12,345'). Podrazumevano on Primer off	tekst	neobavezno
Sort key	sortable	“on” generates a hidden sort key Primer on	tekst	neobavezno
spell numbers?	spell	If used, spells input or input and output numbers in words, optionally capitalizing the first Primer 'in', 'In', 'on', or 'On'	tekst	neobavezno
singular	sing	If 'yes', uses singular form of units (deprecated) Primer yes	tekst	zastarelo
fraction	frac	fraction as rounding unit	broj	neobavezno
currency symbol	$	sets currency symbol in both units Primer $=€ will show " €10 per mile (€6.2/km)"	tekst	neobavezno
WD property	input	Reeds the property value of the item (article), then converts it Primer {{convert|input=P2046}} (P2046=area)	tekst	neobavezno
