Convert Gigahertz to Hertz

Converting Gigahertz (GHz) to Hertz (Hz) 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 1.0000e+9. Written as an equation: Hz = GHz × 1.0000e+9.

One gigahertz equals approximately 1000000000 Hz. This means you can multiply any GHz value by 1000000000 to get the equivalent in Hz.

Worked example: 10 GHz = 10000000000 Hz. 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.
