The megahertz
The megahertz (MHz) equals exactly 1,000,000 Hz. It is the standard unit for FM radio broadcast frequencies and early computer processor clock speeds.
Megahertz to Gigahertz Converter
1 MHz = 0.001 GHz (megahertz → gigahertz)
1 MHz = 0.001 GHz
1 megahertz equals 0.001 gigahertz. To convert megahertz to gigahertz, multiply the megahertz value by 0.001. For quick reference: 1 MHz = 0.001 GHz, 5 MHz = 0.005 GHz, 10 MHz = 0.01 GHz, 100 MHz = 0.1 GHz.
Formula
Gigahertz = Megahertz × 0.001Quick

Frequently asked questions
- How many gigahertz are in 1 megahertz?
- 1 megahertz equals 0.001 gigahertz.
- How do I convert megahertz to gigahertz?
- Multiply the megahertz value by 0.001. So x MHz × 0.001 = the equivalent in GHz.
- What is 5 megahertz in gigahertz?
- 5 megahertz equals 0.005 gigahertz.
- What is 10 megahertz in gigahertz?
- 10 megahertz equals 0.01 gigahertz.
- What is 100 megahertz in gigahertz?
- 100 megahertz equals 0.1 gigahertz.
- How do I convert back from gigahertz to megahertz?
- Multiply the gigahertz value by 1000. For example, 1 GHz = 1000 MHz.
- Is the megahertz bigger than the gigahertz?
- No. 1 megahertz is smaller than 1 gigahertz. It takes 1000 megahertz to equal 1 gigahertz.
- Are these conversion factors exact?
- The factor is derived directly from the SI definitions of megahertz and gigahertz; the displayed value is rounded for readability, and the browser computes using IEEE 754 double-precision arithmetic.
