Popular frequency conversions
| Conversion | Rate |
|---|---|
| Revolutions Per Minute to hertz | 1 rpm = 0.016666667 Hz |
| Hertz to revolutions per minute | 1 Hz = 60 rpm |
| Megahertz to gigahertz | 1 MHz = 0.001 GHz |
| Kilohertz to hertz | 1 kHz = 1,000 Hz |
About frequency units
One hertz is one cycle per second. Rotational speed in rpm is cycles per minute, so divide rpm by 60 to get hertz.

Frequency unit definitions
- Hertz (Hz)
- The hertz is the SI unit of frequency, one cycle per second.
- Kilohertz (kHz)
- A kilohertz is 1,000 hertz. AM radio stations broadcast in kHz.
- Megahertz (MHz)
- A megahertz is 1,000,000 hertz. FM radio and older processors are rated in MHz.
- Gigahertz (GHz)
- A gigahertz is 1,000,000,000 hertz. Processor clock speeds and Wi-Fi bands are given in GHz.
- Revolution Per Minute (rpm)
- Revolutions per minute counts full turns per minute. One rpm is 1/60 of a hertz.
