Convert hertz to megahertz
Converting hertz to megahertz is a common frequency task, whether you are checking a recipe, a spec sheet, a travel distance or a homework problem. Since 1 Hz equals 0.000001 MHz, the math is a single multiplication — and this page does it for you instantly, with the formula, a table of common values and answers to the questions people ask most.
Exact factor
How to convert hertz to megahertz
To convert hertz to megahertz, multiply the number of hertz by 0.000001. For example, 10 Hz × 0.000001 = 0.00001 MHz.
MHz = Hz × 0.000001
- Write down the value in hertz you want to convert.
- Multiply it by 0.000001 (the exact Hz→MHz factor).
- The result is your value in megahertz. Check it below with the converter or the table.

About these units
Hertz (Hz). The hertz is the SI unit of frequency: one cycle per second. It is named after Heinrich Hertz and measures everything from mains electricity (50–60 Hz) to musical pitch.
Megahertz (MHz). A megahertz is one million cycles per second. FM radio occupies 88–108 MHz, and older CPU clocks, memory buses and shortwave bands are measured in MHz.
