Angular acceleration is the rate of change of angular velocity. In SI units, it is measured in radians per second squared (rad/s²). This Acceleration (Angular) converter allows you to convert radian/sq. minute (rad/min²), radian/sq. second (rad/s²), revolution/minute-second (rev/min·s), revolution/sq. minute (rev/min²), revolution/sq. second (rev/s²), among other units related to Acceleration (Angular).
