How the conversion works
Multiply by 0.001 to go from hertz to kilohertz, or divide by it to go back. Every conversion on this site routes through the SI value (Hz) rather than a table of pairwise factors, so a round-trip returns exactly what you started with.
Going the other way? kilohertz to hertz — 1 kHz = 1,000 Hz.
