Angular (or rotational) speed is the rotation rate of a spinning object. It is the angle through which the object turns per unit of time.
Common measures of angles include degrees, radians, and revolutions (the number of complete 360-degree turns). A common unit of angular speed is the number of revolutions per minute (RPM). Other useful measures are both revolutions (or cycles) per second and radians per second, which are commonly used for other periodic phenomena such electrical signals, sound waves, and electromagnetic waves.
Some representative angular speeds can be found in the article on benchmark quantities.
