About Converting Kilohertz to Gigahertz
Kilohertz and Gigahertz both describe how fast something cycles or rotates, and the conversion is a routine part of reading a car tachometer or motor spec sheet against a scientific frequency figure. Specifically: Kilohertz is 1000 hertz units, and gigahertz is 1000000000 hertz units.
Formula
gigahertz = kilohertz × 0.000001
This factor comes from each unit's defined relationship to the category's base unit: 1 kilohertz equals 1000 base units, and 1 gigahertz equals 1000000000 base units, so dividing one by the other gives the direct kilohertz-to-gigahertz factor of 0.000001.
Simple example
1 kHz × 0.000001 = 0.000001 GHz
1 kilohertz = 0.000001 gigahertz.
Real-world example
1,000 kHz × 0.000001 = 0.001 GHz
1,000 kilohertz = 0.001 gigahertz.

Reverse conversion: Gigahertz to Kilohertz
0.000001 GHz × 1000000 = 1 kHz
0.000001 gigahertz = 1 kilohertz.
kilohertz = gigahertz × 1000000

Frequently asked questions
How many gigahertz are in 1 kilohertz?
1 kilohertz equals 0.000001 gigahertz, using the exact defined conversion factor rather than an estimate.
How do I convert kilohertz to gigahertz?
Multiply the kilohertz value by 0.000001. The converter above does this instantly to whatever precision you set.
How do I convert gigahertz back to kilohertz?
Use the reverse factor: 1 gigahertz equals 1,000,000 kilohertz. You can also use the swap control in the converter above to flip the direction instantly.
What is a kilohertz?
Kilohertz (kHz) is a unit of frequency.
What is a gigahertz?
Gigahertz (GHz) is a unit of frequency.
Is the kilohertz to gigahertz conversion exact?
Yes. Both kilohertz and gigahertz are defined by fixed standards rather than physical artifacts, so the factor of 0.000001 used above is exact to as many digits as you choose to display.
