Formula
GHz = MHz ÷ 1,000
Hertz measures how many times something happens per second. One megahertz is a million cycles per second; one gigahertz is a billion. A processor running at 3,200 MHz is a 3.2 GHz processor.
Where you see MHz and GHz
- Processors: clock speeds of 2–6 GHz; a higher clock means more cycles per second, but architecture and core count matter just as much.
- Memory (RAM): often listed in MHz or MT/s, e.g. DDR5-6000.
- Wi-Fi: the 2.4 GHz, 5 GHz and 6 GHz bands.
- Radio: FM broadcasting at 87.5–108 MHz.
