About these units
Revolutions per Minute (rpm): Revolutions per minute (rpm) measures rotational speed of engines, fans, drives and turntables.
Radians per Second (rad/s): Radians per second measures angular velocity. One full revolution per second is 2π rad/s.
Frequently asked questions
How many radians per second are in 1 revolution per minute?
1 revolution per minute (rpm) equals 0.1047197551 radians per second (rad/s).
How do I convert rpm to rad/s?
Multiply the value in revolutions per minute by 0.1047197551. For example, 5 rpm × 0.1047197551 = 0.5235987756 rad/s.
How do I convert radians per second back to revolutions per minute?
Multiply by 9.549296586 (or divide by 0.1047197551). 1 rad/s = 9.549296586 rpm.
What does rpm mean?
Revolutions per minute (rpm) measures rotational speed of engines, fans, drives and turntables.
