Radian per hour
The radian per hour (symbol: rad/h) is an angular velocity unit expressing change in orientation measured in radians over an hour. Since a full circle comprises 2 pi radians, one radian per hour equals approximately 57.296 degrees per hour or 2.78 x 10^-4 radians per second. It is primarily used in orbital mechanics, astrodynamics, and oceanography to describe the slow angular rates of celestial orbits and tidal ocean currents.
