Kilohertz to hertz conversion

A kilohertz is a thousand hertz, so moving from kilohertz to hertz means multiplying by 1000. Type the frequency in kHz, press Convert, and the matching value in hertz appears right away.

How to convert kHz to Hz

Enter the frequency in kilohertz and press Convert. The number is multiplied by the factor 1000 and the answer is shown in hertz. Copy keeps the result handy, Clear empties the field for the next figure.

The same relationship runs the other way: 1 kHz equals 1000 Hz and 1 Hz equals 0.001 kHz, so dividing a hertz value by 1000 brings you back to kilohertz.

kHz to Hz formula

Take the frequency expressed in kilohertz and multiply it by 1000; the outcome is that same frequency expressed in hertz:

f(Hz) = f(kHz) × 1000

For a frequency of 3 kilohertz: 3 kHz × 1000 = 3000 Hz.
