khz to ghz | Exact Decimal + Formula
1 Kilohertz = 0.000001 Gigahertz
One gigahertz equals exactly a million kilohertz. Real-world use: am radio bands and ultrasonic applications. This page expresses those values in gigahertz, which is used for modern processor speeds, wi-fi bands (2.4/5/6 ghz), and radar. Type a value above for an instant answer; the exact formula and the reference table are below.
About Kilohertz and Gigahertz

kHz to GHz Formula and Examples
Direct Formula
GHz = kHz × 1.000000e-6 Inverse Formula
kHz = GHz × 1000000 Mental Math Shortcut
Divide the value by roughly 1000000 to quickly estimate the converted result.
Common Kilohertz to Gigahertz Calculations
- 5 kHz = 0.000005 GHz
- 10 kHz = 0.00001 GHz
- 50 kHz = 0.00005 GHz
- 100 kHz = 0.0001 GHz
- 500 kHz = 0.0005 GHz
Precision & Practical Use
For example, 10 kHz = 0.00001 GHz — roughly fractional unit measurement.
Results are computed to up to 9 decimal places. Round to the precision of your measuring instrument — for most frequency applications, 2–3 significant figures are plenty.

How to Convert Kilohertz to Gigahertz
How many gigahertzes are in one kilohertz?
One Kilohertz (kHz) equals 0.000001 Gigahertz (GHz). To convert kilohertzes to gigahertzes, multiply the kilohertz value by 0.000001.
How do I convert Kilohertz to Gigahertz?
Multiply your kilohertz value by 0.000001 to get the result in Gigahertz: GHz = kHz × 0.000001. For example, 5 kHz = 0.000005 GHz.
What is the formula for converting kHz to GHz?
The conversion formula is GHz = kHz × 0.000001. Use the calculator above for any value, and see the reference table below for common inputs from 0.001 to 1000.
Is there a quick mental estimate for kHz to GHz?
Divide the value by roughly 1000000 to quickly estimate the converted result.
