Frequency, Revolutions per minute

Revolutions per minute (abbreviated rpm, RPM, r/min, or r·min⁻¹) is a unit of frequency: the number of full rotations completed in one minute around a fixed axis. It is most commonly used as a measure of rotational speed or angular velocity of some mechanical component. Read more
