Hertz to Kilohertz Converter

1 hertz (Hz) equals 0.001 kilohertz (kHz).

Quick answer

  • 1 hertz = 0.001 kilohertz
  • 1 kilohertz = 1,000 hertz
  • Formula: kHz = Hz ÷ 1,000

1 hertz = 0.001 kilohertz

How to convert hertz to kilohertz

kHz = Hz ÷ 1,000

To convert hertz to kilohertz, divide the number of hertz by 1,000.

Example: 42 Hz to kHz

  1. Start with the value in hertz: 42 Hz.
  2. Divide by 1,000: 42 ÷ 1,000 = 0.042.
  3. Result: 42 hertz = 0.042 kilohertz.

Going the other way, 1 kilohertz = 1,000 hertz, so to convert kilohertz back to hertz you multiply by the same number. See kilohertz to hertz.

What is a kilohertz?

The kilohertz is 1,000 hertz. It is used for audio (the upper limit of human hearing is about 20 kHz), AM radio (530–1,700 kHz in the Americas) and sampling rates (44.1 kHz CD audio).
