How do I convert RPM to Hz?

To convert RPM to hertz, divide by 60: 3,000 RPM = 50 Hz. One hertz is one cycle (or revolution) per second.

Examples

  • 3,000 RPM motor = 50 Hz
  • FM radio 100 MHz = 100,000,000 Hz
  • Wi-Fi 2.4 GHz = 2,400 MHz
  • 1 Hz = 6.283 rad/s (2π)

Useful for electronics, audio, motors, radio and physics problems.
