Convert Megahertz to Gigahertz (MHz to GHz)
1 megahertz (MHz) = 0.001 gigahertz (GHz). 1 GHz = 1000 MHz. Example: 2400 MHz = 2400 × 0.001 = 2.4 GHz.
Also searched as MHz to GHz, megahertz to gigahertz and mhz in ghz.
1 MHz = 0.001 GHz

How to Convert Megahertz to Gigahertz
- 1 MHz = 0.001 GHz
- 1 GHz = 1000 MHz
- Example: convert 2400 MHz to GHz: 2400 MHz = 2400 × 0.001 GHz = 2.4 GHz
Formula
GHz = MHz ÷ 1000
Derivation from SI units:
- 1 MHz = 10⁶ Hz.
- 1 GHz = 10⁹ Hz.
- 1 MHz = 1000000 Hz ÷ 1000000000 Hz per GHz = 0.001 GHz
Both units are defined exactly, so the factor is exact. Megahertz definition: megahertz; Gigahertz definition: gigahertz.
Worked examples
- A 2400 MHz Wi-Fi channel is 2.4 GHz.
2400 MHz × 0.001 = 2.4 GHz - A 3600 MHz processor clock is 3.6 GHz.
3600 MHz × 0.001 = 3.6 GHz
