Convert Hertz to Gigahertz
Hz to GHz · frequency conversion
What are hertz and gigahertz?
The hertz is the SI unit of frequency, one cycle per second. A gigahertz is one billion hertz, typical for modern CPU and Wi-Fi frequencies. For reference: human hearing spans about 20 Hz to 20 kHz, and Wi-Fi runs at 2.4–5 GHz.
How to convert hertz to gigahertz
1 Hz = 1.0000e-9 GHz. To convert, multiply the number of hertz by 1.0000e-9. For example, 5 Hz = 5.0000e-9 GHz, and 20 Hz = 2.0000e-8 GHz. To go the other way, multiply gigahertz by 1,000,000,000 (since 1 GHz = 1,000,000,000 Hz).

FAQ
What is 1 Hz in GHz?
1 Hz = 1.0000e-9 GHz. To convert any amount, multiply the number of hertz by 1.0000e-9.
How do I convert gigahertz back to hertz?
Go the other way: 1 GHz = 1,000,000,000 Hz, so multiply gigahertz by 1,000,000,000 to get hertz.
Is a hertz bigger than a gigahertz?
No — 1 Hz is the smaller unit, equal to 1.0000e-9 GHz (it takes 1,000,000,000 Hz to make one GHz).
Are these frequency conversions exact?
They use the standard internationally-defined conversion factors. Results are rounded to six significant figures for readability, which is accurate enough for everyday and most technical use.
