Convert Kilohertz to Gigahertz (kHz to GHz)
1 kilohertz (kHz) = 0.000001 gigahertz (GHz). 1 GHz = 1000000 kHz. Example: 15 kHz = 15 × 0.000001 = 0.000015 GHz.

How to Convert Kilohertz to Gigahertz
- 1 kHz = 0.000001 GHz
- 1 GHz = 1000000 kHz
- Example: convert 15 kHz to GHz: 15 kHz = 15 × 0.000001 GHz = 0.000015 GHz
Formula
GHz = kHz ÷ 1000000
Derivation from SI units:
- 1 kHz = 10³ Hz.
- 1 GHz = 10⁹ Hz.
- 1 kHz = 1000 Hz ÷ 1000000000 Hz per GHz = 0.000001 GHz
Both units are defined exactly, so the factor is exact. Kilohertz definition: kilohertz; Gigahertz definition: gigahertz.
Worked examples
- A reading of 16 kHz converts to 0.000016 GHz.
16 kHz × 0.000001 = 0.000016 GHz - A value of 48 kHz is 0.000048 GHz.
48 kHz × 0.000001 = 0.000048 GHz

Where it's used
Kilohertz are used for audio sample rates, while gigahertz appear in CPU and GPU clock speeds. Both measure frequency and rotational speed, so the conversion is a fixed factor.

Frequently asked questions
How many gigahertz are in 1 kilohertz?
1 kHz = 0.000001 GHz.
How do I convert kilohertz to gigahertz?
Multiply the value in kHz by 0.000001, or divide it by 1000000. For example, 15 kHz × 0.000001 = 0.000015 GHz.
Is the kHz to GHz conversion exact?
Yes. Both units are defined exactly, and 1 kHz is exactly 0.000001 GHz.
