kHz to MHz Converter
Convert kilohertz to megahertz instantly. 1 kHz = 0.001 MHz, worked steps and a full reference table.
How to use it
- Type the value in kilohertz — 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 kHz | 0.001 MHz |
| 5 kHz | 0.005 MHz |
| 10 kHz | 0.01 MHz |
| 100 kHz | 0.1 MHz |
One kilohertz equals 0.001 megahertzes (MHz). To convert kilohertzes to megahertzes, multiply by 0.001; to go back the other way, multiply by 1000 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 kilohertzes and megahertzes actually measure
Kilohertz (kHz) — A kilohertz is a thousand hertz. Audio sampling and AM radio.
Megahertz (MHz) — A megahertz is a million hertz. FM radio, older processor speeds and RF work.
kHz to MHz conversion table
The most common values, worked out in advance. Anything not listed can be typed straight into the converter.
| kHz | MHz |
|---|---|
| 1 kHz | 0.001 MHz |
| 2 kHz | 0.002 MHz |
| 5 kHz | 0.005 MHz |
| 10 kHz | 0.01 MHz |
| 25 kHz | 0.025 MHz |
| 50 kHz | 0.05 MHz |
| 100 kHz | 0.1 MHz |
How to convert kilohertzes to megahertzes by hand
Multiply the number of kilohertzes by 0.001.
For example, 25 kHz × 0.001 = 0.025 MHz.
Going the other way, divide by 0.001 — or multiply by 1000, 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 kHz?
1 kHz equals exactly 0.001 MHz. Multiply any value in kilohertz by 0.001 to get megahertz.
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.
