Convert kilohertz to gigahertz
Converting kilohertz to gigahertz is a common frequency task, whether you are checking a recipe, a spec sheet, a travel distance or a homework problem. Since 1 kHz equals 0.000001 GHz, 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 kilohertz to gigahertz
To convert kilohertz to gigahertz, multiply the number of kilohertz by 0.000001. For example, 10 kHz × 0.000001 = 0.00001 GHz.
GHz = kHz × 0.000001
- Write down the value in kilohertz you want to convert.
- Multiply it by 0.000001 (the exact kHz→GHz factor).
- The result is your value in gigahertz. Check it below with the converter or the table.

About these units
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.
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.
Frequently asked questions
How do I convert kilohertz to gigahertz?
To convert kilohertz to gigahertz, multiply the number of kilohertz by 0.000001. For example, 10 kHz × 0.000001 = 0.00001 GHz. Or skip the math: type the value into the converter at the top of this page and the result updates instantly.
