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

About the units
Hertz (Hz)
One cycle per second.
Gigahertz (GHz)
CPU clock speeds and Wi-Fi bands are given in GHz. One gigahertz equals 1,000,000,000 hertz (Hz).
Frequently asked questions
How many gigahertz are in one hertz?
There are 1×10⁻⁹ gigahertz in one hertz, and this value is exact by definition.
How do I convert hertz to gigahertz?
Multiply the number of hertz by 1×10⁻⁹. For example, 10 Hz × 1×10⁻⁹ = 1×10⁻⁸ GHz.
How many hertz are in one gigahertz?
One gigahertz equals 1,000,000,000 hertz. That is the reverse factor, 1 ÷ 1×10⁻⁹.
What is 10 hertz in gigahertz?
10 Hz = 1×10⁻⁸ GHz.
Is this Hz to GHz 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.
