Convert Kilohertz to Gigahertz
1 kilohertz is 0.000001 GHz. One kilohertz is exactly 0.000001 gigahertz.
One kilohertz is 1.0000 × 10^-6 gigahertz. To convert kilohertz to gigahertz, multiply by 1.0000 × 10^-6; to go the other way, divide by 1.0000 × 10^-6 or multiply by 1000000. The relation is exact but the figure is not: it is a rounding of a number that does not terminate, and it follows from NIST Special Publication 811. A thousand hertz.

1 kilohertz in every frequency unit
| Unit | Value | Exact factor |
|---|---|---|
| hertz | 1,000 Hz | × 1,000 |
| kilohertz (as entered) | 1 kHz | — |
| megahertz | 0.001 MHz | × 0.001 |
| gigahertz | 0.000001 GHz | × 0.000001 |
| terahertz | 0.000000001 THz | × 0.000000001 |
| revolutions per minute | 60,000 rpm | × 60,000 |
Factors are entered by hand from NIST Special Publication 811 rather than derived from a units library, so the ones that terminate are exact rather than rounded.
How do you convert kilohertz to gigahertz? The converter and the working
- 1.Take the measurement in kilohertz.
- 2.Multiply by 1.0000 × 10^-6 — that is how many gigahertz fit in one kilohertz.
- 3.To go back the other way, divide by 1.0000 × 10^-6, or multiply by 1000000.
Worked example: 25 kilohertz to gigahertz
- Formula
- kHz × 1.0000 × 10^-6 = GHz
- Arithmetic
- 25 × 1.0000 × 10^-6 = 0.000025 GHz
- Answer
- 25 kHz = 0.000025 GHz
The factor is rounded for display; the figure above is computed from the full value.

What is a kilohertz?
A thousand hertz. AM radio is broadcast here — 540 to 1600 kHz — and audio sampling is quoted in it: a CD samples at 44.1 kHz.
What is a gigahertz?
A billion hertz. Wi-Fi runs at 2.4 and 5 GHz, and a processor clock has been quoted in these since about 2000 — a 3.5 GHz core starts a new cycle every 286 picoseconds.
How many gigahertz are in a kilohertz?
One kilohertz is 1.0000 × 10^-6 gigahertz. Going the other way, one gigahertz is 1000000 kilohertz. Both figures come from the same defined relation rather than from a measurement, which is why they are the same today as they were in 1959.
Every frequency unit here
The whole group — 6 units with their symbols and the size of each one in hertzs — is on the conversion index, along with every pair it makes. The table above already gives each of them relative to a kilohertz.
