Hz to MHz Converter
Convert hertz (Hz) to megahertz (MHz) instantly. Type a value — the result updates as you type, and the swap button converts the other way.
Hz to MHz formula
MHz = Hz ÷ 1000000
1 hertz = 0.000001 megahertz · 1 megahertz = 1000000 hertz
To convert hertz to megahertz, divide the value by 1000000. For example, 1000000 Hz:
MHz = 1000000 ÷ 1000000MHz = 1
So 1000000 Hz = 1 MHz.
Mental math shortcut
This conversion is exact, so there is no need to estimate: just divide by 1,000,000.

About the units
Hertz (Hz)
A hertz is one cycle per second — the unit of frequency for sound, radio and electricity.
Megahertz (MHz)
A megahertz is one million hertz. FM radio and older processors are measured in MHz.
