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. 


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.

How to convert Hertz to Kilohertz

1 Hz = 0.001 kHz. To convert any value, multiply it by 0.001. For example, 25 Hz = 0.025 kHz.

Frequently asked questions
How many kHz are there in one Hz?
One Hz is equal to 0.001 kHz.
How do you convert Hertz to Kilohertz?
Multiply the value in Hertz by 0.001 to get the result in Kilohertz.
How much is 25 Hz in kHz?
25 Hz is equal to 0.025 kHz.
How do you convert Kilohertz back to Hertz?
Divide by the same factor: multiply the value in Kilohertz by 1000 to get Hertz.
