How to convert Hertz to Kilohertz
To convert Hertz to Kilohertz, multiply the value by the conversion factor 0.001. To go the other way, multiply by 1,000 (or divide by 0.001).
Worked example: 50 Hz to kHz
- Write the value: 50 Hz
- Multiply by 0.001: 50 × 0.001
- Result: 0.05 kHz

About Hertz and Kilohertz
What is a hertz (Hz)?
One hertz is one cycle per second. Bangladesh mains electricity runs at 50 Hz.
What is a kilohertz (kHz)?
A kilohertz equals 1,000 Hz, used for AM radio and audio.
Where hertz to kilohertz conversion is used
Frequency conversions are needed for radio, processors, audio, electrical systems and motors. Converting between Hertz and Kilohertz is especially common when you compare products, read foreign specifications, or fill in forms that expect a specific unit.

Frequently asked questions
How many Kilohertz are in 1 hertz?
1 Hertz equals 0.001 kHz.
How do I convert Hertz to Kilohertz?
Multiply the number of Hertz by 0.001. For example, 50 Hz × 0.001 = 0.05 kHz.
What is 50 Hz in kHz?
50 Hz = 0.05 kHz.
How many Hertz are in 1 kilohertz?
1 Kilohertz equals 1,000 Hz. Use the kHz to Hz converter for the reverse direction.
