How to convert megahertz to kilohertz
kHz = MHz × 1,000Multiply the value in megahertz by 1,000. To go the other way, multiply by 0.001 (or divide by 1,000).
A megahertz is larger than a kilohertz: one megahertz contains 1,000 kilohertz.
Worked examples
- 1 megahertz1 MHz × 1,000 = 1,000 kHz
- 5 megahertz5 MHz × 1,000 = 5,000 kHz
- 10 megahertz10 MHz × 1,000 = 10,000 kHz
- 20 megahertz20 MHz × 1,000 = 20,000 kHz
- 100 megahertz100 MHz × 1,000 = 100,000 kHz

About the units
Megahertz (MHz)
The megahertz (MHz) is a unit of frequency in the International System of Units (SI). One megahertz equals 1,000,000 hertz (Hz).
Kilohertz (kHz)
The kilohertz (kHz) is a unit of frequency in the International System of Units (SI). One kilohertz equals 1,000 hertz (Hz).
Frequently asked questions
How many kilohertz are in one megahertz?
There are 1,000 kilohertz in one megahertz, and this value is exact by definition.
How do I convert megahertz to kilohertz?
Multiply the number of megahertz by 1,000. For example, 10 MHz × 1,000 = 10,000 kHz.
How many megahertz are in one kilohertz?
One kilohertz equals 0.001 megahertz. That is the reverse factor, 1 ÷ 1,000.
What is 10 megahertz in kilohertz?
10 MHz = 10,000 kHz.
Is this MHz to kHz converter accurate?
Yes. Both units are defined exactly in terms of SI units, so the conversion factor is exact; results are shown to 12 significant figures by default and you can change precision in the converter. Calculations run in your browser using the same tested engine that generated this page.
