Convert kHz to Hz
Input the number of kilohertz you want to convert to hertz.
How to Convert Kilohertz to Hertz
The kilohertz and hertz are both units of frequency. By definition, 1 kilohertz equals exactly 1000 hertz. This means to convert kilohertz to hertz, you multiply by 1000.
Formula
Step-by-Step Example
Convert 5 kHz to hertz:
We need to convert kilohertz to hertz
Since 1 kHz = 1000 Hz, multiply by 1000
5 × 1000 = 5000
5 kHz = 5000 Hz

About These Units
Kilohertz (kHz)
A kilohertz (kHz) equals 1,000 hertz. Kilohertz measures AM radio frequencies (530-1700 kHz), ultrasonic cleaning (20-40 kHz), and audio sample rates (44.1 kHz for CD quality). Human hearing upper limit is about 20 kHz.
Hertz (Hz)
The hertz (Hz) is the SI unit of frequency equal to one cycle per second. Hertz measures sound pitch (human hearing: 20-20,000 Hz), AC power (50/60 Hz), and oscillations. Middle C on a piano is 261.63 Hz. Named after physicist Heinrich Hertz.
