The gigahertz
The gigahertz (GHz) equals exactly 1,000,000,000 Hz. It is the standard unit for modern CPU clock speeds and Wi-Fi/cellular radio bands.
Gigahertz to Hertz Converter
1 GHz = 1000000000 Hz (gigahertz → hertz)
1 GHz = 1000000000 Hz
1 gigahertz equals 1000000000 hertz. To convert gigahertz to hertz, multiply the gigahertz value by 1000000000. For quick reference: 1 GHz = 1000000000 Hz, 5 GHz = 5000000000 Hz, 10 GHz = 10000000000 Hz, 100 GHz = 100000000000 Hz.
Formula
Hertz = Gigahertz × 1000000000Quick

- Are these conversion factors exact?
- The factor is derived directly from the SI definitions of gigahertz and hertz; the displayed value is rounded for readability, and the browser computes using IEEE 754 double-precision arithmetic.
About the gigahertz and the hertz
The hertz
The hertz (Hz) is the SI derived unit of frequency, equal to one cycle per second. It is the universal unit for sound pitch, electrical AC frequency, processor clock speed (in multiples), and radio and wireless signal frequencies.
