How to convert gigahertz to kilohertz
kHz = GHz × 1,000,000Multiply the value in gigahertz by 1,000,000. To go the other way, multiply by 0.000001 (or divide by 1,000,000).
A gigahertz is larger than a kilohertz: one gigahertz contains 1,000,000 kilohertz.
Worked examples

- 5 gigahertz5 GHz × 1,000,000 = 5,000,000 kHz
- 10 gigahertz10 GHz × 1,000,000 = 10,000,000 kHz
- 20 gigahertz20 GHz × 1,000,000 = 20,000,000 kHz
- 100 gigahertz100 GHz × 1,000,000 = 100,000,000 kHz

About the units
Gigahertz (GHz)
CPU clock speeds and Wi-Fi bands are given in GHz. One gigahertz equals 1,000,000,000 hertz (Hz).
Kilohertz (kHz)
The kilohertz (kHz) is a unit of frequency in the International System of Units (SI). One kilohertz equals 1,000 hertz (Hz).
Frequently asked questions
How many kilohertz are in one gigahertz?
There are 1,000,000 kilohertz in one gigahertz, and this value is exact by definition.
How do I convert gigahertz to kilohertz?
Multiply the number of gigahertz by 1,000,000. For example, 10 GHz × 1,000,000 = 10,000,000 kHz.
How many gigahertz are in one kilohertz?
One kilohertz equals 0.000001 gigahertz. That is the reverse factor, 1 ÷ 1,000,000.
What is 10 gigahertz in kilohertz?
10 GHz = 10,000,000 kHz.
Is this GHz to kHz converter accurate?
Yes. Both units are defined exactly in terms of SI units, so the conversion factor is exact; results are shown to 12 significant figures by default and you can change precision in the converter. Calculations run in your browser using the same tested engine that generated this page.
