Convert Megahertz to Hertz
MHz to Hz · frequency conversion
What are megahertz and hertz?
A megahertz is one million hertz, used for radio bands and processor clock speeds. 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 megahertz to hertz
1 MHz = 1,000,000 Hz. To convert, multiply the number of megahertz by 1,000,000. For example, 5 MHz = 5,000,000 Hz, and 20 MHz = 20,000,000 Hz. To go the other way, multiply hertz by 0.000001 (since 1 Hz = 0.000001 MHz).

FAQ
What is 1 MHz in Hz?
1 MHz = 1,000,000 Hz. To convert any amount, multiply the number of megahertz by 1,000,000.
How do I convert hertz back to megahertz?
Go the other way: 1 Hz = 0.000001 MHz, so multiply hertz by 0.000001 to get megahertz.
Is a megahertz bigger than a hertz?
Yes — 1 MHz is the larger unit, equal to 1,000,000 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.
