Frequently Asked Questions

What does radian/hour measure?
Radian per hour measures how quickly an angle changes, representing slow angular velocity as radians rotated over one hour.

How is revolution/second related to radians per second?
One revolution per second equals 2π radians per second, directly representing the frequency of full rotations per time.

Why convert from radian/hour to revolution/second?
Converting helps translate slow rotation rates into a higher-resolution frequency useful for comparing with faster rotating systems.

Key Terminology

Radian/hour [rad/h]
A unit of angular velocity indicating one radian of rotation occurring over an hour, used to measure slow rotation speeds.
Revolution/second [r/s]
A unit of angular speed describing how many full rotations an object completes in one second.
