Kilohertz to hertz
Type a value in kHz to get it in Hz instantly.
That's 5× as fast as the top of human hearing, while AM radio is 10× faster. As a radio wave, one wave would be 2.998 km long.
Convert the other way: Hz to kHz
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 kHz to Hz
To convert kilohertz to hertz, multiply by 1,000.
Example: 100 kHz × 1,000 = 100,000 Hz.
In the other direction, 1 Hz = 0.001 kHz.

About these units
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.
Hertz (Hz)
One hertz is one cycle per second. It is the SI unit of frequency and the base for every multiple below.
