How the conversion works
1 Hz = 1 cycle/second. 1 rpm = 1/60 Hz. CPU/radio frequencies typically expressed in MHz or GHz.
When you'll use this converter
- Radio and wireless (MHz, GHz)
- Audio engineering (Hz, kHz)
- CPU clock speed (GHz)
- Motor and engine speed (rpm)
Frequently asked
How many Hz in 1 rpm?
1 rpm = 1/60 Hz ≈ 0.01667 Hz. So 3,000 rpm = 50 Hz.
What's the frequency range of human hearing?
Roughly 20 Hz to 20,000 Hz (20 kHz), reducing with age.
