Input multiples

The following tables define composite input units consisting of multiple unit codes. A composite must consist of two unit codes where the second is a subdivision of the first. In addition, a default output must be specified. Optionally, an alternate unit code or name can be specified. An alternate unit must have the same scale as that of the subdivision, but may have a different name or symbol.

If both an alternate unit and name are provided, the unit will be used when the input consists of only two components, and the alternate name will be used with three or more (generally, the alternate name would be shorter than the unit's standard name or symbol, and that may be desirable when three or more units make up an input composite).

If an alternate name is used, it replaces the unit's symbol and name and plural name. In other words, the same alternate name applies regardless of whether the unit is abbreviated, and regardless of the number of units.

If the unit yd allows ft as a subdivision, and ft allows in, then the input to a conversion can use all three units (for example, {{convert|1|yd|2|ft|3|in}} which specifies the input as 1 yard, 2 feet, 3 inches). There is no limit to the number of units that can be used in an input multiple.

To simplify processing by the script which extracts data from this wikitext, a unit code is required in the first column; that unit code is not used. This section is read after all units and combinations are defined, so the unit codes may refer to items defined anywhere on this page.

Output multiples

The following tables define the "multiple" unit codes that can be used for an output unit. Using a multiple code for the output means that the conversion result contains multiple components (for example, a length expressed in yards, feet, inches).

Combinations

The following tables list predefined "combination" unit codes that can be used for an output unit. Using a combination code for the output means that the input value is converted to more than one unit. In addition to the combinations listed here, units may be combined by separating unit codes with a space or plus character.

Automatic per units

The following table defines equivalent unit types for some of the types that can be generated automatically for unit codes of the form x/y (x per y). For example, the unit code kg/hl is not defined, so if it were used, it would be regarded as kilograms per hectolitre with unit type mass/volume; the following table would translate that to density so the unit could be converted with other density units. If "Density" is specified in the Link column, the unit name or symbol would be linked to Density if |lk=on is used.

In addition, a scale multiplier can be specified; that allows mass/area units to be converted to pressure units on the assumption that the mass refers to the force due to the "weight" of an object.

Type/type	Equivalent unit type	Link	Multiplier
/area	per unit area
/volume	per unit volume
area/area	area per unit area
energy/length	energy per unit length
energy/mass	energy per unit mass
energy/time	power	Power (physics)
energy/volume	energy per unit volume
force/area	pressure	Pressure
length/length	gradient	Grade (slope)
length/time	speed	Speed
length/time/time	acceleration	Acceleration
mass/area	pressure		9.80665
mass/length	linear density
mass/mass	concentration
mass/power	mass per unit power
mass/time	mass per unit time
mass/volume	density	Density
power/mass	power per unit mass
power/volume		Power density
pressure/length	fracture gradient
speed/time	acceleration	Acceleration
volume/area	volume per unit area
volume/length	volume per unit length
volume/time	flow

Overrides

The following tables define "override" unit codes which conflict with another unit when it is combined with one of the SI prefixes. The script which processes this page rejects unit codes that duplicate a known entry, however, that checking is not performed for the unit codes listed here. The Comment field documents the conflict, but is otherwise ignored.

Area

Override code	Comment
daa	Override default prefix which would give name "decaare".
ha	Override default prefix which would give name "hectoare".

Mass

Override code	Comment
MT	For "metric ton", not "megatesla".

Pressure

Override code	Comment
Pa	For "Pascal", not "peta-are".
