MHz to GHz – convert megahertz to gigahertz
Convert MHz to GHz (megahertz to gigahertz) for Wi-Fi, 5G and mobile networks, radar and other high-frequency electronics. This page opens the main frequency converter with MHz → GHz pre-selected.
Open the interactive MHz → GHz converter:
Use main converter (MHz → GHz) or switch to GHz → MHzOn the homepage you can also drop down to Hz, kHz and up again to GHz using a single unified frequency tool.
Quick reference: MHz to GHz
1 gigahertz is 1,000 megahertz. The conversion is:
GHz = MHz ÷ 1000
| MHz | GHz |
|---|---|
| 100 MHz | 0.1 GHz |
| 500 MHz | 0.5 GHz |
| 1000 MHz | 1 GHz |
| 1800 MHz | 1.8 GHz |
| 2400 MHz | 2.4 GHz |
| 5000 MHz | 5 GHz |
Why convert MHz to GHz?
Use MHz → GHz when you:
- Compare datasheets that quote frequencies in different units.
- Summarise cellular or Wi-Fi band plans in GHz for presentations.
- Scale lab measurements from MHz up to GHz for RF design work.
- Check whether a given MHz value sits inside a GHz-labelled band.
