Convert Kilohertz to Megahertz (kHz to MHz)
1 kilohertz (kHz) = 0.001 megahertz (MHz). 1 MHz = 1000 kHz. Example: 15 kHz = 15 × 0.001 = 0.015 MHz.

How to Convert Kilohertz to Megahertz
- 1 kHz = 0.001 MHz
- 1 MHz = 1000 kHz
- Example: convert 15 kHz to MHz: 15 kHz = 15 × 0.001 MHz = 0.015 MHz
Formula
MHz = kHz ÷ 1000
Derivation from SI units:
- 1 kHz = 10³ Hz.
- 1 MHz = 10⁶ Hz.
- 1 kHz = 1000 Hz ÷ 1000000 Hz per MHz = 0.001 MHz
Both units are defined exactly, so the factor is exact. Kilohertz definition: kilohertz; Megahertz definition: megahertz.
Worked examples
- A reading of 16 kHz converts to 0.016 MHz.
16 kHz × 0.001 = 0.016 MHz - A value of 48 kHz is 0.048 MHz.
48 kHz × 0.001 = 0.048 MHz

Where it's used
Kilohertz are used for audio sample rates, while megahertz appear in FM radio and TV. Both measure frequency and rotational speed, so the conversion is a fixed factor.

Frequently asked questions
How many megahertz are in 1 kilohertz?
1 kHz = 0.001 MHz.
How do I convert kilohertz to megahertz?
Multiply the value in kHz by 0.001, or divide it by 1000. For example, 15 kHz × 0.001 = 0.015 MHz.
Is the kHz to MHz conversion exact?
Yes. Both units are defined exactly, and 1 kHz is exactly 0.001 MHz.
