Hertz to kilohertz
Type a value in Hz to get it in kHz instantly.
That's 1.67× as fast as a 60 Hz screen, while concert pitch A is 4.4× faster. As sound in air, one wave would be 3.43 m long.
Convert the other way: kHz to Hz
What it means
What does that look like?
The wavelength shown is for sound in air at 20 °C (343 m/s). Radio waves travel at the speed of light, so their wavelengths are far longer.
The math
How to convert Hz to kHz
To convert hertz to kilohertz, multiply by 0.001.
Example: 100 Hz × 0.001 = 0.1 kHz.
In the other direction, 1 kHz = 1,000 Hz.

About these units
Hertz (Hz)
One hertz is one cycle per second. It is the SI unit of frequency and the base for every multiple below.
Kilohertz (kHz)
A kilohertz is 1,000 cycles per second. Human hearing tops out around 20 kHz, and AM radio sits in the hundreds of kHz.
