Frequently asked questions
How many kilohertz are in one megahertz?
One megahertz equals 1,000 kilohertz. 1,000 is the exact factor used by this converter.
How do I convert megahertz to kilohertz?
Multiply the value in megahertz by 1,000. To go the other way, multiply kilohertz by 0.001.
What is 10 MHz in kHz?
10 MHz = 10,000 kHz. Also, 5 MHz = 5,000 kHz and 100 MHz = 100,000 kHz.
What is the difference between a megahertz and a kilohertz?
A megahertz is one million hertz, used for FM radio and older CPUs. A kilohertz is 1,000 Hz, common for AM radio and audio.
