Kilohertz to Hertz Converter

How to convert kilohertz to hertz

1. 1

   Take your value

   Start with your value in kilohertz.

2. 2

   Multiply by 1000

   Multiply the kilohertz value by 1000. This is the exact conversion factor from kilohertz to hertz.

3. 3

   Read the result

   The product is your value in hertz. For example, 5 kHz × 1000 = 5000 Hz.

Conversion formula

The exact factor from kilohertz to hertz is 1000.

Real-world reference

CD-quality audio is sampled at 44.1 kHz. AM radio stations broadcast in the range of 530–1,700 kHz. In hertz, that gives you: 1 kHz = 1000 Hz, 10 kHz = 10000 Hz, 100 kHz = 100000 Hz.

Frequently asked questions

How many hertz are in 1 kilohertz?

1 kilohertz equals 1000 hertz.

How do I convert kilohertz to hertz?

Multiply the kilohertz value by 1000. So x kHz × 1000 = the equivalent in Hz.

What is 5 kilohertz in hertz?

5 kilohertz equals 5000 hertz.

What is 10 kilohertz in hertz?

10 kilohertz equals 10000 hertz.

What is 100 kilohertz in hertz?

100 kilohertz equals 100000 hertz.

How do I convert back from hertz to kilohertz?

Multiply the hertz value by 0.001. For example, 1 Hz = 0.001 kHz.

Is the kilohertz bigger than the hertz?

Yes. 1 kilohertz is larger than 1 hertz — specifically 1000 times larger.

Are these conversion factors exact?

The factor is derived directly from the SI definitions of kilohertz and hertz; the displayed value is rounded for readability, and the browser computes using IEEE 754 double-precision arithmetic.
