The gigahertz
The gigahertz (GHz) equals exactly 1,000,000,000 Hz. It is the standard unit for modern CPU clock speeds and Wi-Fi/cellular radio bands.
Gigahertz to Megahertz Converter
1 GHz = 1000 MHz (gigahertz → megahertz)
1 GHz = 1000 MHz
1 gigahertz equals 1000 megahertz. To convert gigahertz to megahertz, multiply the gigahertz value by 1000. For quick reference: 1 GHz = 1000 MHz, 5 GHz = 5000 MHz, 10 GHz = 10000 MHz, 100 GHz = 100000 MHz.
Formula
Megahertz = Gigahertz × 1000Quick

Real-world reference
Modern desktop CPUs typically run at 3–5 GHz. Wi-Fi commonly operates in the 2.4 GHz and 5 GHz bands. In megahertz, that gives you: 1 GHz = 1000 MHz, 10 GHz = 10000 MHz, 100 GHz = 100000 MHz.
Frequently asked questions
- How many megahertz are in 1 gigahertz?
- 1 gigahertz equals 1000 megahertz.
- How do I convert gigahertz to megahertz?
- Multiply the gigahertz value by 1000. So x GHz × 1000 = the equivalent in MHz.
- What is 5 gigahertz in megahertz?
- 5 gigahertz equals 5000 megahertz.
- What is 10 gigahertz in megahertz?
- 10 gigahertz equals 10000 megahertz.
- What is 100 gigahertz in megahertz?
- 100 gigahertz equals 100000 megahertz.
- How do I convert back from megahertz to gigahertz?
- Multiply the megahertz value by 0.001. For example, 1 MHz = 0.001 GHz.
- Is the gigahertz bigger than the megahertz?
- Yes. 1 gigahertz is larger than 1 megahertz — specifically 1000 times larger.
- Are these conversion factors exact?
- The factor is derived directly from the SI definitions of gigahertz and megahertz; the displayed value is rounded for readability, and the browser computes using IEEE 754 double-precision arithmetic.
