How to Convert Gigahertz to Hertz
The gigahertz and hertz are both units of frequency. By definition, 1 gigahertz equals exactly 1000000000 hertz. This means to convert gigahertz to hertz, you multiply by 1000000000.
Formula
Step-by-Step Example
Convert 5 GHz to hertz:
We need to convert gigahertz to hertz
Since 1 GHz = 1000000000 Hz, multiply by 1000000000
5 × 1000000000 = 5000000000
5 GHz = 5000000000 Hz

About These Units
Gigahertz (GHz)
A gigahertz (GHz) equals 1 billion hertz. Gigahertz measures modern CPU speeds (2-5 GHz), WiFi (2.4 GHz, 5 GHz, 6 GHz), 5G cellular (millimeter wave: 24-47 GHz), and microwave ovens (2.45 GHz). RAM speed is also measured in GHz.
Hertz (Hz)
The hertz (Hz) is the SI unit of frequency equal to one cycle per second. Hertz measures sound pitch (human hearing: 20-20,000 Hz), AC power (50/60 Hz), and oscillations. Middle C on a piano is 261.63 Hz. Named after physicist Heinrich Hertz.
