Convert Hz to kHz
Type the number of hertz that you wish to convert to kilohertz.
How to Convert Hertz to Kilohertz
The hertz and kilohertz are both units of frequency. By definition, 1 kilohertz equals exactly 1000 hertz. This means to convert hertz to kilohertz, you divide by 1000.
Formula
Step-by-Step Example
Convert 5 Hz to kilohertz:
We need to convert hertz to kilohertz
Since 1 kHz = 1000 Hz, divide by 1000
5 ÷ 1000 = 0.005
5 Hz = 0.005 kHz

About These Units
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.
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.
Frequently Asked Questions
How do I convert hertz to kilohertz?
To convert hertz to kilohertz, divide the value by 1000. For example, 10 Hz = 0.01 kHz.
How many kilohertz are in 1 hertz?
1 hertz equals 0.001 kilohertz.
What is the formula for hertz to kilohertz?
The formula is: kHz = Hz ÷ 1000.
