Kilohertz

The kilohertz (kHz) is a unit of frequency equal to 10³ hertz (one thousand cycles per second). It is used to measure AM radio frequencies (530–1700 kHz), audio sampling rates, and ultrasonic frequencies. The range of human hearing extends up to approximately 20 kHz. 


Hertz

The hertz (Hz) is the SI unit of frequency, defined as one cycle per second. It is named after the German physicist Heinrich Hertz. Frequencies in everyday life range from a few hertz for sound waves to gigahertz for radio waves and processor clock speeds, and into terahertz for infrared light.

How to convert Kilohertz to Hertz

1 kHz = 1000 Hz. To convert any value, multiply it by 1000. For example, 25 kHz = 25000 Hz.
