How many MHz is 1 GHz?

1 GHz equals exactly 1000 MHz. The "giga-" prefix means 10^9, while "mega-" means 10^6, so the ratio is always 10^3 = 1000.

Is 2400 MHz the same as 2.4 GHz?

Yes. 2400 MHz ÷ 1000 = 2.4 GHz. The 2.4 GHz Wi-Fi band channels typically span roughly 2400–2500 MHz.

My CPU is listed as 3600 MHz — how many GHz is that?

3600 MHz ÷ 1000 = 3.6 GHz. Most modern desktop CPUs run between 3 GHz and 6 GHz (3000–6000 MHz).

Can I convert GHz back to MHz with this tool?

This tool converts MHz → GHz. To go the other way, multiply your GHz value by 1000, or search for a GHz to MHz converter.

Why do spec sheets sometimes use MHz instead of GHz?

MHz avoids decimal points for values below 1 GHz, making them easier to read. 850 MHz is cleaner than 0.85 GHz. Both representations are equally correct.

Megahertz to Gigahertz Converter

Summary

The megahertz to gigahertz converter applies the exact SI prefix relationship: 1 gigahertz equals exactly 1000 megahertz, so dividing an MHz value by 1000 gives GHz. This tool accepts any MHz value — from sub-1 MHz audio frequencies up to multi-thousand MHz processor clocks — and instantly displays the equivalent in GHz, kilohertz, and hertz for full context. It is useful for reading CPU and GPU spec sheets, Wi-Fi and 5G band tables, radio spectrum charts, and oscillator datasheets.

How it works
