Kilohertz to Hertz Converter

A kilohertz (kHz) is a unit of frequency equal to one thousand hertz (10³ Hz). It represents moderate frequencies commonly found in audio applications, low-frequency radio, and various electronic systems.

The kilohertz became important with the development of audio technology and early radio communications. It provided a convenient scale for describing audio frequencies and low-frequency radio waves, becoming essential in the development of broadcasting and audio equipment.

Kilohertz is extensively used in audio engineering, AM radio broadcasting, audio equipment specifications, and low-frequency electronic applications. It's standard for describing audio frequency ranges, AM radio frequencies, and various audio processing equipment.

A hertz (Hz) is the SI base unit of frequency, defined as one cycle per second. It represents the fundamental measure of frequency, named after German physicist Heinrich Hertz, and forms the basis for all other frequency measurements.

The hertz was named after Heinrich Hertz in 1930, who proved the existence of electromagnetic waves. It was adopted as the SI unit of frequency in 1960, replacing the older term 'cycles per second' and providing a unified measure for all periodic phenomena.

Hertz is universally used for measuring all types of frequencies, from sound waves to electromagnetic radiation. It's fundamental in physics, engineering, music, and technology, serving as the base unit for all frequency measurements and calculations.
