What is angular velocity?

Angular velocity (ω) measures how fast an object rotates, expressed as angle per time. SI unit is rad/s; engineering often uses RPM (revolutions per minute).

How do I convert RPM to rad/s?

Multiply RPM by 2π/60 ≈ 0.10472. For example, 1 000 RPM × 0.10472 = 104.72 rad/s.

What is the relationship between angular velocity and linear velocity?

v = ω × r, where v is linear velocity (m/s), ω is angular velocity (rad/s), and r is the radius (m).

Convert between all common angular velocity units in three groups: Radians (rad/s, rad/min, rad/hr, mrad/s), Degrees (°/s, °/min, °/hr), and Revolutions (rev/s, RPM, rev/hr). Includes real-world reference speeds for hard drives, jet turbines, car wheels, Earth rotation, and RC helicopter rotors. Adjustable significant figures, scientific notation toggle, swap, per-row copy.

How to Use

1Enter an angular speed value in the From field and choose the source unit (e.g. RPM)
2Select the target unit in the To dropdown (e.g. rad/s) to see the instant result
3Browse Radians, Degrees, and Revolutions groups in the results panel
4Hover any row and click Copy or ↕ to copy or set as input
5Click the swap button ⇄ to reverse the conversion direction
6Open the Reference panel for real-world rotational speeds
