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

FAQ
What is 1 GHz in Hz?
1 GHz = 1,000,000,000 Hz. To convert any amount, multiply the number of gigahertz by 1,000,000,000.
How do I convert hertz back to gigahertz?
Go the other way: 1 Hz = 1.0000e-9 GHz, so multiply hertz by 1.0000e-9 to get gigahertz.
Is a gigahertz bigger than a hertz?
Yes — 1 GHz is the larger unit, equal to 1,000,000,000 Hz.
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.
