Convert Megahertz to Kilohertz
MHz to kHz · frequency conversion
What are megahertz and kilohertz?
A megahertz is one million hertz, used for radio bands and processor clock speeds. A kilohertz is 1,000 hertz, used for audio and radio frequencies. For reference: human hearing spans about 20 Hz to 20 kHz, and Wi-Fi runs at 2.4–5 GHz.
How to convert megahertz to kilohertz
1 MHz = 1,000 kHz. To convert, multiply the number of megahertz by 1,000. For example, 5 MHz = 5,000 kHz, and 20 MHz = 20,000 kHz. To go the other way, multiply kilohertz by 0.001 (since 1 kHz = 0.001 MHz).

FAQ
What is 1 MHz in kHz?
1 MHz = 1,000 kHz. To convert any amount, multiply the number of megahertz by 1,000.
How do I convert kilohertz back to megahertz?
Go the other way: 1 kHz = 0.001 MHz, so multiply kilohertz by 0.001 to get megahertz.
Is a megahertz bigger than a kilohertz?
Yes — 1 MHz is the larger unit, equal to 1,000 kHz.
Are these frequency conversions exact?
They use the standard internationally-defined conversion factors. Results are rounded to six significant figures for readability, which is accurate enough for everyday and most technical use.
