# what is Hertz? How we convert kilohertz to Hertz (kHz to Hz) with Examples

## Hertz

Hertz is the SI (International System of Units)  of unit frequency. It is the derived unit  that express in Hz. Hertz is defined as cycles per one second. It is commonly expressed in multiples: kilohertz (103 Hz, kHz), megahertz (106 Hz, MHz), gigahertz (109 Hz, GHz), terahertz (1012 Hz, THz), petahertz (1015 Hz, PHz). v

This unit are sometimes also used for energy, like the photon energy equation (E=hν), with one hertz equivalent to h joules.

## How we convert kilohertz to Hertz (kHz to Hz)

1kHz = 1000Hz

or

1Hz = 0.001kHz

### Kilohertz to hertz formula

The frequency in hertz (Hz) is equal to the frequency in kilohertz (kHz) times 1000:

f(Hz) = f(kHz) × 1000

### Example

Convert 4 kilohertz to hertz:

f(Hz) = 4kHz × 1000 = 4000Hz
