How to convert Megahertz to Gigahertz
To convert megahertz to gigahertz, multiply by 0.001. One megahertz equals 0.001 GHz, and one gigahertz equals 1,000 MHz.
- Take the value in megahertz — for example 7.5 MHz.
- Multiply by 0.001 (the number of gigahertz in one megahertz).
- 7.5 × 0.001 = 0.0075 GHz.
Shortcut: the factor is a power of ten, so just move the decimal point 3 places to the left.
