What is the difference between MHz and GHz?

1 GHz (gigahertz) equals 1,000 MHz (megahertz). A 2.4 GHz WiFi signal is the same as 2,400 MHz.

How do I convert Hz to RPM?

Multiply hertz by 60 to get RPM (revolutions per minute). For example, 50 Hz = 3,000 RPM.

What frequency is audible to humans?

Humans can typically hear frequencies between 20 Hz and 20,000 Hz (20 kHz). This range decreases with age.

About Frequency Conversion

Frequency measures how often something repeats per unit of time. The hertz (Hz) is the SI unit — 1 Hz means one cycle per second. Radio stations broadcast in megahertz (MHz) and gigahertz (GHz), processors run at GHz speeds, and sound waves are measured in Hz and kHz.

Convert between hertz, kilohertz, megahertz, gigahertz, terahertz, and RPM instantly. Useful for electronics, radio, music, and physics.
