Kilohertz (kHz)
The kilohertz (symbol: kHz) is a decimal multiple of the hertz, equal to one thousand cycles per second (10^3 Hz). Formally adopted by the International Electrotechnical Commission in 1930 and integrated into the SI system in 1960 to replace cycles per second, the unit honors German physicist Heinrich Hertz. Kilohertz is extensively used in audio engineering, ultrasonic applications, AM radio broadcasting, and low-frequency communications.
