Frequently asked questions
How many megahertz are in one kilohertz?
One kilohertz equals 0.001 megahertz. 0.001 is the exact factor used by this converter.
How do I convert kilohertz to megahertz?
Multiply the value in kilohertz by 0.001. To go the other way, multiply megahertz by 1,000.
What is 10 kHz in MHz?
10 kHz = 0.01 MHz. Also, 5 kHz = 0.005 MHz and 100 kHz = 0.1 MHz.
What is the difference between a kilohertz and a megahertz?
A kilohertz is 1,000 Hz, common for AM radio and audio. A megahertz is one million hertz, used for FM radio and older CPUs.
