MHz to kHz Converter
Convert megahertz to kilohertz instantly. 1 MHz = 1000 kHz, 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 | 1000 kHz |
| 5 MHz | 5000 kHz |
| 10 MHz | 10000 kHz |
| 100 MHz | 100000 kHz |
One megahertz equals 1000 kilohertzes (kHz). To convert megahertzes to kilohertzes, multiply by 1000; to go back the other way, multiply by 0.001 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 kilohertzes actually measure
Megahertz (MHz) — A megahertz is a million hertz. FM radio, older processor speeds and RF work.
Kilohertz (kHz) — A kilohertz is a thousand hertz. Audio sampling and AM radio.
MHz to kHz conversion table
The most common values, worked out in advance. Anything not listed can be typed straight into the converter.
| MHz | kHz |
|---|---|
| 1 MHz | 1000 kHz |
| 2 MHz | 2000 kHz |
| 5 MHz | 5000 kHz |
| 10 MHz | 10000 kHz |
| 25 MHz | 25000 kHz |
| 50 MHz | 50000 kHz |
| 100 MHz | 100000 kHz |
How to convert megahertzes to kilohertzes by hand
Multiply the number of megahertzes by 1000.
For example, 25 MHz × 1000 = 25000 kHz.
Going the other way, divide by 1000 — or multiply by 0.001, 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 kHz are in 1 MHz?
1 MHz equals exactly 1000 kHz. Multiply any value in megahertz by 1000 to get kilohertz.
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.
