Convert **radian/hour** to **revolution/minute (rpm)**

Selected category: frequency and angular frequency.

Radian per hour (rad/hr) is a unit of angular frequency equal to 1/(2 x π x 3600) Hz, or 1/(2 x π x 3600) rps. Angular frequency, or angular speed is the magnitude of the vector quantity angular velocity.

Revolutions per minute (rpm) is a unit of frequency, defined as a full rotation around a fixed axis completed in one minute. Rpm is used as a measure of rotational speed of a mechanical component.

Swap, do a revolution/minute (rpm) to radian/hour conversion.
