As we know One r/min is equal to 0.1047197551 rad/s (1 r/min = 0.1047197551 rad/s).

To convert Revolution/minute to Radian/second, multiply your r/min figure by 0.1047197551.

Example : convert 25 r/min to rad/s:

25 r/min = 25 × 0.1047197551 rad/s = rad/s

To convert Radian/second to Revolution/minute, divide your rad/s figure by 0.1047197551.

Example : convert 25 rad/s to r/min:

25 rad/s = 25 ÷ 0.1047197551 r/min = r/min
