How to convert gigahertz to hertz
Hz = GHz × 1,000,000,000Multiply the value in gigahertz by 1,000,000,000. To go the other way, multiply by 1×10⁻⁹ (or divide by 1,000,000,000).
A gigahertz is larger than a hertz: one gigahertz contains 1,000,000,000 hertz.

About the units
Gigahertz (GHz)
CPU clock speeds and Wi-Fi bands are given in GHz. One gigahertz equals 1,000,000,000 hertz (Hz).
Hertz (Hz)
One cycle per second.
Frequently asked questions
How many hertz are in one gigahertz?
There are 1,000,000,000 hertz in one gigahertz, and this value is exact by definition.
How do I convert gigahertz to hertz?
Multiply the number of gigahertz by 1,000,000,000. For example, 10 GHz × 1,000,000,000 = 10,000,000,000 Hz.
How many gigahertz are in one hertz?
One hertz equals 1×10⁻⁹ gigahertz. That is the reverse factor, 1 ÷ 1,000,000,000.
What is 10 gigahertz in hertz?
10 GHz = 10,000,000,000 Hz.
Is this GHz to Hz converter accurate?
Yes. Both units are defined exactly in terms of SI units, so the conversion factor is exact; results are shown to 12 significant figures by default and you can change precision in the converter. Calculations run in your browser using the same tested engine that generated this page.
