Convert Gigahertz to Megahertz

Converting Gigahertz (GHz) to Megahertz (MHz) is a common task in frequency measurements. Frequency conversions relate to radio waves, processor clock speeds, and audio pitch — from hertz through gigahertz.

To convert, multiply the gigahertz value by 1000. Written as an equation: MHz = GHz × 1000.

One gigahertz equals approximately 1000 MHz. This means you can multiply any GHz value by 1000 to get the equivalent in MHz.

Worked example: 100 GHz = 100000 MHz. Enter your own value in the converter above for instant results.

Common mistake: Always include the correct prefix (kilo-, mega-, giga-) — confusing MHz with GHz leads to errors of a thousandfold.
