Convert Megahertz to Gigahertz
MHz to GHz · frequency conversion
What are megahertz and gigahertz?
A megahertz is one million hertz, used for radio bands and processor clock speeds. 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 megahertz to gigahertz
1 MHz = 0.001 GHz. To convert, multiply the number of megahertz by 0.001. For example, 5 MHz = 0.005 GHz, and 20 MHz = 0.02 GHz. To go the other way, multiply gigahertz by 1,000 (since 1 GHz = 1,000 MHz).

FAQ
What is 1 MHz in GHz?
1 MHz = 0.001 GHz. To convert any amount, multiply the number of megahertz by 0.001.
How do I convert gigahertz back to megahertz?
Go the other way: 1 GHz = 1,000 MHz, so multiply gigahertz by 1,000 to get megahertz.
Is a megahertz bigger than a gigahertz?
No — 1 MHz is the smaller unit, equal to 0.001 GHz (it takes 1,000 MHz 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.
