kilohertz [kHz] to hertz [Hz] Converter

Quick Reference

1 kilohertz (kHz) = 1000 hertz (Hz)

1 hertz (Hz) = 0.001 kilohertz (kHz)

How to Convert kilohertz to hertz

1 kHz = 1000 Hz
1 Hz = 0.001 kHz

To convert kilohertz to hertz, multiply the value by 1000. To convert hertz back to kilohertz, divide by 1000.

Example: convert 10 kHz to Hz:
10 kHz = 10 x 1000 = 10000 Hz

↔ Convert hertz to kilohertz

kilohertz

Definition: A kilohertz (symbol: kHz) is a unit of frequency equal to one thousand (1000) hertz (Hz). The hertz, in turn, is the SI unit of frequency, defined as one cycle per second.

History/origin: The kilohertz is derived from the hertz, named after the German physicist Heinrich Hertz, who made significant contributions to the understanding of electromagnetic waves. The prefix 'kilo-' denotes a factor of 10<sup>3</sup>, adhering to the SI system of units.

Current use: Kilohertz is used to measure frequencies in the range of audio signals, radio waves (particularly AM radio), and some computer hardware components. It is a common unit in electronics, telecommunications, and signal processing.

hertz

Definition: Hertz (symbol: Hz) is the SI unit of frequency, defined as the number of cycles per second of a periodic phenomenon. One hertz is equivalent to one cycle or event per second.

History/origin: The hertz is named after Heinrich Hertz, a German physicist who proved the existence of electromagnetic waves in the late 19th century. The unit was adopted as a standard unit for frequency in the 20th century.

Current use: Hertz is widely used across various fields to measure frequency, including radio waves, audio signals, computer processing speeds, alternating current (AC) electricity, and any oscillating or repeating phenomenon. It's a fundamental unit in physics, engineering, and technology.
