How to convert kilohertz to hertz

One kilohertz equals 1000 Hz, so multiply the number of kilohertzs by 1000:

Hz = kHz × 1000

Going the other way

One hertz equals 0.001 kHz, so to convert back:

kHz = Hz × 0.001

Both directions are shown in the results above, and the drop-downs let you convert between any pair of frequency units — not just these two.
