How to convert hertz to kilohertz
kHz = Hz × 0.001Multiply the value in hertz by 0.001. To go the other way, multiply by 1,000 (or divide by 0.001).
A hertz is smaller than a kilohertz: it takes 1,000 hertz to make one kilohertz.
Worked examples
- 1 hertz1 Hz × 0.001 = 0.001 kHz
- 5 hertz5 Hz × 0.001 = 0.005 kHz
- 10 hertz10 Hz × 0.001 = 0.01 kHz
- 20 hertz20 Hz × 0.001 = 0.02 kHz
- 100 hertz100 Hz × 0.001 = 0.1 kHz

About the units
Hertz (Hz)
One cycle per second.
Kilohertz (kHz)
The kilohertz (kHz) is a unit of frequency in the International System of Units (SI). One kilohertz equals 1,000 hertz (Hz).
Frequently asked questions
How many kilohertz are in one hertz?
There are 0.001 kilohertz in one hertz, and this value is exact by definition.
How do I convert hertz to kilohertz?
Multiply the number of hertz by 0.001. For example, 10 Hz × 0.001 = 0.01 kHz.
How many hertz are in one kilohertz?
One kilohertz equals 1,000 hertz. That is the reverse factor, 1 ÷ 0.001.
What is 10 hertz in kilohertz?
10 Hz = 0.01 kHz.
Is this Hz to kHz converter accurate?
Yes. Both units are defined exactly in terms of SI units, so the conversion factor is exact; results are shown to 12 significant figures by default and you can change precision in the converter. Calculations run in your browser using the same tested engine that generated this page.
