About the Angular Velocity Converter
Angular velocity measures how fast an object rotates — the angle swept per unit time. Revolutions per minute (RPM) is the everyday unit for motors and engines. Radians per second is the standard in physics and mathematics because it integrates naturally with linear velocity formulas. The relationship between linear and angular velocity is v = ω × r (velocity equals angular velocity times radius).
Quick facts
- ›A car engine at highway speed typically runs at 2,000–3,000 RPM
- ›A hard disk drive (HDD) spins at 5,400 or 7,200 RPM
- ›The Earth rotates at approximately 0.0000727 rad/s (one rotation per sidereal day)
- ›A dentist's drill can reach 400,000 RPM
