ghz to khz | Exact Decimal + Formula
1 Gigahertz = 1000000 Kilohertz
One gigahertz equals exactly a million kilohertz. Real-world use: modern processor speeds, wi-fi bands (2.4/5/6 ghz), and radar. This page expresses those values in kilohertz, which is used for am radio bands and ultrasonic applications. Type a value above for an instant answer; the exact formula and the reference table are below.

GHz to kHz Formula and Examples
Direct Formula
kHz = GHz × 1000000 Inverse Formula
GHz = kHz × 0.000001 Mental Math Shortcut
Multiply the value by roughly 1000000 to calculate the equivalent amount in your head.
Common Gigahertz to Kilohertz Calculations
- 5 GHz = 5000000 kHz
- 10 GHz = 10000000 kHz
- 50 GHz = 50000000 kHz
- 100 GHz = 100000000 kHz
- 500 GHz = 500000000 kHz
Precision & Practical Use
For example, 10 GHz = 10000000 kHz — roughly multiple unit increments.
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 Gigahertz to Kilohertz
How many kilohertzes are in one gigahertz?
One Gigahertz (GHz) equals 1000000 Kilohertz (kHz). To convert gigahertzes to kilohertzes, multiply the gigahertz value by 1000000.
How do I convert Gigahertz to Kilohertz?
Multiply your gigahertz value by 1000000 to get the result in Kilohertz: kHz = GHz × 1000000. For example, 5 GHz = 5000000 kHz.
What is the formula for converting GHz to kHz?
The conversion formula is kHz = GHz × 1000000. 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 GHz to kHz?
Multiply the value by roughly 1000000 to calculate the equivalent amount in your head.
