MHz to Hz Converter
Convert megahertz to hertz instantly. 1 MHz = 1000000 Hz, worked steps and a full reference table.
How to use it
- Type the value in megahertz — 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 MHz | 1000000 Hz |
| 5 MHz | 5000000 Hz |
| 10 MHz | 10000000 Hz |
| 100 MHz | 100000000 Hz |
One megahertz equals 1000000 hertzes (Hz). To convert megahertzes to hertzes, multiply by 1000000; to go back the other way, multiply by 1.0000e-6 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 megahertzes and hertzes actually measure
Megahertz (MHz) — A megahertz is a million hertz. FM radio, older processor speeds and RF work.
Hertz (Hz) — The hertz is one cycle per second. Mains supply, audio pitch and refresh rates.

How to convert megahertzes to hertzes by hand
Multiply the number of megahertzes by 1000000.
For example, 25 MHz × 1000000 = 25000000 Hz.
Going the other way, divide by 1000000 — or multiply by 1.0000e-6, 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 Hz are in 1 MHz?
1 MHz equals exactly 1000000 Hz. Multiply any value in megahertz by 1000000 to get hertz.
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.
