Example

Example: convert 20000 hertz to kilohertz.

20000 Hz = 20 kHz

Conversion table

hertz (Hz) kilohertz (kHz)
1 Hz 0.001 kHz
2 Hz 0.002 kHz
5 Hz 0.005 kHz
10 Hz 0.01 kHz
20 Hz 0.02 kHz
50 Hz 0.05 kHz
100 Hz 0.1 kHz

Explanation

These are both units.

How to convert hertz to kilohertz

  1. Start with the value in hertz (Hz).
  2. Multiply it by 0.001.
  3. The result is the measurement in kilohertz (kHz).

Example: 20000 Hz → 20 kHz

Frequently Asked Questions

How much is 20000 hertz in kilohertz?

What is the difference between hertz and kilohertz?

They measure the same quantity, but they may belong to different systems or be used in different contexts depending on region.

Where are hertz and kilohertz used?

They are used in electronics, audio, radio, and communications to describe signals and oscillations; the most practical unit depends on the frequency scale.

Why does 1 hertz equal 0.001 kilohertz?

Because the “kilo-” prefix means 1000. One kilohertz equals 1000 hertz.
