Kilohertz (kHz)

Definition

A kilohertz (kHz) is a unit of frequency equal to 1,000 hertz. It represents one thousand cycles per second.

History

The kilohertz replaced the older term 'kilocycle' (kc) when the SI system adopted the hertz in 1960. It was widely used in early radio broadcasting to describe AM radio frequencies and audio sampling rates.

Current use

Kilohertz is commonly used in AM radio broadcasting, audio engineering, ultrasonic applications, and sonar technology. Audio sampling rates and some communication protocols are specified in kHz.

Hertz (Hz)

Definition

A hertz (Hz) is the SI unit of frequency, defined as one cycle per second. It measures how often a periodic event occurs in one second.

History

The hertz was named after Heinrich Hertz, the German physicist who first proved the existence of electromagnetic waves in 1887. The unit was officially adopted by the CGPM in 1960, replacing the earlier term 'cycles per second' (cps).

Current use

Hertz is universally used to measure frequency in electronics, telecommunications, acoustics, and physics. Clock speeds, radio frequencies, sound pitch, and alternating current are all expressed in hertz or its multiples.
