convert/unit_name

convert units to unit names

 

Calling Sequence

Parameters

Description

Compatibility

Calling Sequence

convert(u, unit_name)

Parameters

u

-

expression with units

Description

• 

The convertu,unit_name function returns a representation of the unit part of the expression u that can be easily manipulated programmatically.

• 

First this procedure determines the unit of u. Then every unit name or symbol in this unit expression is replaced by the function call Units:-UnitNamestring form of the full unit name. The unit-free factor, if present, is ignored.

• 

If there are annotations, then the base unit name (including its context, if applicable) is converted to a string; the resulting string is applied, as a function call, to the string form of the annotations.

• 

The recommended way to convert units to a particular system or otherwise control the format of units is to do this before calling convert...,unit_name, using commands such as combine and convert.

Examples

The unit-free factor is ignored.

Notes: 

– 

To enter a unit in 2-D Math input, select the unit from the appropriate Units palette. If the unit you want is not there, select unit and then enter the unit.

– 

In Maple 2015 and later versions, the double brackets around a unit are not displayed unless you are editing the unit.

(1)

You always get the full name (farad), even if you supply only the symbol (F). Prefixes are respected.

convert2uF,'unit_name'

Units:-UnitNamemicrofarad

(2)

Contexts or annotations are also maintained.

Units:-UnitNamemile[nautical]radius

(3)

In case you would prefer units to be converted to a particular system, it is best to do that before the conversion to unit names.
