Kilohertz Unit | All you need to know
The kilohertz (symbol: kHz) is an SI-derived unit of frequency equal to one thousand (103) hertz. It is commonly used to measure the frequency of audio signals, radio transmissions, ultrasonic waves, electronic circuits, and digital communication systems. The kilohertz uses the SI prefix kilo, which represents a factor of one thousand.
One kilohertz is equal to 1,000 hertz, 0.001 megahertz, 0.000001 gigahertz, 60,000 revolutions per minute, and 6,283.185307 radians per second. The kilohertz is widely used in electronics, broadcasting, telecommunications, and signal processing.
