Convert Hertz to Kilohertz
Hz to kHz · frequency conversion
What are hertz and kilohertz?
The hertz is the SI unit of frequency, one cycle per second. A kilohertz is 1,000 hertz, used for audio and radio frequencies. For reference: human hearing spans about 20 Hz to 20 kHz, and Wi-Fi runs at 2.4–5 GHz.
How to convert hertz to kilohertz
1 Hz = 0.001 kHz. To convert, multiply the number of hertz by 0.001. For example, 5 Hz = 0.005 kHz, and 20 Hz = 0.02 kHz. To go the other way, multiply kilohertz by 1,000 (since 1 kHz = 1,000 Hz).

FAQ
What is 1 Hz in kHz?
1 Hz = 0.001 kHz. To convert any amount, multiply the number of hertz by 0.001.
How do I convert kilohertz back to hertz?
Go the other way: 1 kHz = 1,000 Hz, so multiply kilohertz by 1,000 to get hertz.
Is a hertz bigger than a kilohertz?
No — 1 Hz is the smaller unit, equal to 0.001 kHz (it takes 1,000 Hz to make one kHz).
Are these frequency conversions exact?
They use the standard internationally-defined conversion factors. Results are rounded to six significant figures for readability, which is accurate enough for everyday and most technical use.
