Convert Hertz to Megahertz
Hz to MHz · frequency conversion
What are hertz and megahertz?
The hertz is the SI unit of frequency, one cycle per second. 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 hertz to megahertz
1 Hz = 0.000001 MHz. To convert, multiply the number of hertz by 0.000001. For example, 5 Hz = 0.000005 MHz, and 20 Hz = 0.00002 MHz. To go the other way, multiply megahertz by 1,000,000 (since 1 MHz = 1,000,000 Hz).

FAQ
What is 1 Hz in MHz?
1 Hz = 0.000001 MHz. To convert any amount, multiply the number of hertz by 0.000001.
How do I convert megahertz back to hertz?
Go the other way: 1 MHz = 1,000,000 Hz, so multiply megahertz by 1,000,000 to get hertz.
Is a hertz bigger than a megahertz?
No — 1 Hz is the smaller unit, equal to 0.000001 MHz (it takes 1,000,000 Hz to make one 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.
