Convert gigahertz to kilohertz
Converting gigahertz to kilohertz 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 kHz, 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 kilohertz
To convert gigahertz to kilohertz, multiply the number of gigahertz by 1,000,000. For example, 10 GHz × 1,000,000 = 10,000,000 kHz.
kHz = GHz × 1,000,000
- Write down the value in gigahertz you want to convert.
- Multiply it by 1,000,000 (the exact GHz→kHz factor).
- The result is your value in kilohertz. 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.
Kilohertz (kHz). A kilohertz is 1,000 hertz. AM radio broadcasts sit around 500–1,700 kHz, human hearing spans roughly 20 Hz to 20 kHz, and audio sample rates are quoted in kHz.
Frequently asked questions
