How it works

One hertz is one cycle per second. Prefixes multiply by 1,000: kHz, MHz, GHz. For rotating machines, 1 RPM = 1/60 Hz, so an engine at 3,000 RPM turns 50 times per second.

Examples

Wi-Fi: 2.4 GHz = 2,400 MHz.
Motor: 1,500 RPM = 25 Hz.

Common uses

Radio and Wi-Fi

Frequently asked questions

How do I get the period from the frequency?

Period (s) = 1 ÷ frequency (Hz). 50 Hz → 0.02 s.

Is RPM a frequency?

Yes, revolutions per minute is a rotational frequency.
