How to Convert Hertz to Megahertz

To convert a hertz measurement to a megahertz measurement, divide the frequency by the conversion ratio.

Since one megahertz is equal to 1,000,000 hertz, you can use this simple formula to convert:

megahertz = hertz ÷ 1,000,000

The frequency in megahertz is equal to the hertz divided by 1,000,000.

For example, here's how to convert 5,000,000 hertz to megahertz using the formula above.
5,000,000 Hz = (5,000,000 ÷ 1,000,000) = 5 MHz

Hertz and megahertz are both units used to measure frequency. Keep reading to learn more about each unit of measure.


Hertz is formally defined as the frequency equalling one cycle per second.[1]

The hertz is the SI derived unit for frequency in the metric system. Hertz can be abbreviated as Hz; for example, 1 hertz can be written as 1 Hz.

Frequency in hertz can be expressed using the formula: Hz = Cycles / Times


Megahertz is a measure of frequency equal to one million cycles per second.

The megahertz is a multiple of the hertz, which is the SI derived unit for frequency. In the metric system, "mega" is the prefix for 106. Megahertz can be abbreviated as MHz; for example, 1 megahertz can be written as 1 MHz.
