About the angular velocity converter

Convert angular velocity between rad/s, deg/s, revolutions per minute (RPM), and revolutions per second. The SI unit is the radian per second. Engineers use RPM for motors, turbines, and rotating machinery; physics and control systems prefer rad/s.

Frequently asked questions

  • How many rad/s is 1 RPM?

    One RPM equals 2π/60 ≈ 0.10472 rad/s.

  • How many RPM is 1 rad/s?

    One rad/s equals 60/(2π) ≈ 9.5493 RPM.

  • How is angular velocity related to linear velocity?

    Linear velocity v = ωr, where ω is angular velocity in rad/s and r is the radius. A 0.3 m wheel spinning at 100 rad/s has rim speed 30 m/s.

  • What is the SI unit of angular velocity?

    The radian per second (rad/s).
