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

FAQ
What is 1 GHz in MHz?
1 GHz = 1,000 MHz. To convert any amount, multiply the number of gigahertz by 1,000.
How do I convert megahertz back to gigahertz?
Go the other way: 1 MHz = 0.001 GHz, so multiply megahertz by 0.001 to get gigahertz.
Is a gigahertz bigger than a megahertz?
Yes — 1 GHz is the larger unit, equal to 1,000 MHz.
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.
