Convert gigahertz to hertz
Converting gigahertz to hertz is a common frequency task, whether you are checking a recipe, a spec sheet, a travel distance or a homework problem. Since 1 GHz equals 1,000,000,000 Hz, the math is a single multiplication — and this page does it for you instantly, with the formula, a table of common values and answers to the questions people ask most.
Exact factor
How to convert gigahertz to hertz
To convert gigahertz to hertz, multiply the number of gigahertz by 1,000,000,000. For example, 10 GHz × 1,000,000,000 = 10,000,000,000 Hz.
Hz = GHz × 1,000,000,000
- Write down the value in gigahertz you want to convert.
- Multiply it by 1,000,000,000 (the exact GHz→Hz factor).
- The result is your value in hertz. Check it below with the converter or the table.

About these units
Gigahertz (GHz). A gigahertz is one billion cycles per second. Modern processors clock at several GHz, and Wi-Fi, 5G and radar systems operate in the gigahertz range.
Hertz (Hz). The hertz is the SI unit of frequency: one cycle per second. It is named after Heinrich Hertz and measures everything from mains electricity (50–60 Hz) to musical pitch.
