Angular speed has the dimension plane angle per time. The SI composite unit of angular speed is the radian per second.

Maple knows the units of angular speed listed in the following table.

An asterisk ( * ) indicates the default context, an at sign (@) indicates an abbreviation, and under the prefixes column, SI indicates that the unit takes all SI prefixes, IEC indicates that the unit takes IEC prefixes, and SI+ and SI- indicate that the unit takes only positive and negative SI prefixes, respectively.  Refer to a unit in the Units package by indexing the name or symbol with the context, for example, mach[standard] or mph[standard]; or, if the context is indicated as the default, by using only the unit name or symbol, for example, mach or mph.

The unit of angular speed is defined as follows.

A revolution per minute is defined as $2\mathrm{\pi }$ radians per minute.
