Hz to MHz Converter
Convert hertz to megahertz instantly. 1 Hz = 0.000001 MHz, worked steps and a full reference table.
How to use it
- Type the value in hertz — the result updates as you type.
- Use Swap to flip the direction, or change either dropdown to convert between any two units.
- Click the result to copy it. The URL updates too, so you can bookmark or share the exact conversion.
Examples
| 1 Hz | 0.000001 MHz |
| 5 Hz | 0.000005 MHz |
| 10 Hz | 0.00001 MHz |
| 100 Hz | 0.0001 MHz |
One hertz equals 1.0000e-6 megahertzes (MHz). To convert hertzes to megahertzes, multiply by 1.0000e-6; to go back the other way, multiply by 1000000 instead.
The converter above does it as you type and shows the working underneath, so you can check the arithmetic rather than take the number on trust.
What hertzes and megahertzes actually measure
Hertz (Hz) — The hertz is one cycle per second. Mains supply, audio pitch and refresh rates.
Megahertz (MHz) — A megahertz is a million hertz. FM radio, older processor speeds and RF work.

How to convert hertzes to megahertzes by hand
Multiply the number of hertzes by 1.0000e-6.
For example, 25 Hz × 1.0000e-6 = 2.5000e-5 MHz.
Going the other way, divide by 1.0000e-6 — or multiply by 1000000, which is the same thing and easier to do in your head.
Everything runs in your browser
There is no server involved in the calculation. The numbers you type never leave your device, nothing is logged, and the page keeps working with no connection once it has loaded. That is not a marketing line — it is simply how the tool is built, because a calculation like this has no reason to touch a network.
Questions people ask
How many MHz are in 1 Hz?

Is anything uploaded to a server?
No. The whole calculation happens in your browser. Nothing is sent anywhere, and the page keeps working offline once loaded.
