About the Angular Velocity Converter

Angular velocity describes how quickly an object rotates, and it is central to motor selection, robotics, machinery, and vibration analysis. Radians per second are the coherent SI unit; one revolution per minute equals 2π/60 rad/s, so 1,800 rpm is 188.4956 rad/s rather than a simple unit-label change.

Choose a source and target unit for an instant result—for example, 60 rpm equals 2π rad/s. Use the Torque & Moment of Force Converter when rotational speed is paired with shaft force, or the Angular Acceleration Converter when the speed is changing.

Frequently asked questions

How do I convert rpm to rad/s?

Multiply rpm by 2π/60. For example, 60 rpm equals 2π rad/s, approximately 6.283185 rad/s.

Is angular velocity the same as rotational speed?

They describe the same rate of rotation, but angular velocity is commonly expressed in rad/s while rotational speed is often reported in rpm.

What is one revolution per second in rpm?

One revolution per second is exactly 60 rpm.
