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

FAQ
What is 1 kHz in Hz?
1 kHz = 1,000 Hz. To convert any amount, multiply the number of kilohertz by 1,000.
How do I convert hertz back to kilohertz?
Go the other way: 1 Hz = 0.001 kHz, so multiply hertz by 0.001 to get kilohertz.
Is a kilohertz bigger than a hertz?
Yes — 1 kHz is the larger unit, equal to 1,000 Hz.
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.
