Convert Megahertz to Kilohertz (MHz to kHz)
1 megahertz (MHz) = 1000 kilohertz (kHz). 1 kHz = 0.001 MHz. Example: 15 MHz = 15 × 1000 = 15000 kHz.

How to Convert Megahertz to Kilohertz
- 1 MHz = 1000 kHz
- 1 kHz = 0.001 MHz
- Example: convert 15 MHz to kHz: 15 MHz = 15 × 1000 kHz = 15000 kHz
Formula
kHz = MHz × 1000
Derivation from SI units:
- 1 MHz = 10⁶ Hz.
- 1 kHz = 10³ Hz.
- 1 MHz = 1000000 Hz ÷ 1000 Hz per kHz = 1000 kHz
Both units are defined exactly, so the factor is exact. Megahertz definition: megahertz; Kilohertz definition: kilohertz.
Worked examples
- A reading of 88 MHz converts to 88000 kHz.
88 MHz × 1000 = 88000 kHz - A value of 433 MHz is 433000 kHz.
433 MHz × 1000 = 433000 kHz

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

Frequently asked questions
How many kilohertz are in 1 megahertz?
1 MHz = 1000 kHz.
How do I convert megahertz to kilohertz?
Multiply the value in MHz by 1000. For example, 15 MHz × 1000 = 15000 kHz.
Is the MHz to kHz conversion exact?
Yes. Both units are defined exactly, and 1 MHz is exactly 1000 kHz.
