terahertz [THz] to kilohertz [kHz] Converter

Quick Reference

1 terahertz (THz) = 1000000000 kilohertz (kHz)

1 kilohertz (kHz) = 1.0000e-9 terahertz (THz)

How to Convert terahertz to kilohertz

1 THz = 1000000000 kHz
1 kHz = 1e-9 THz

To convert terahertz to kilohertz, multiply the value by 1000000000. To convert kilohertz back to terahertz, divide by 1000000000.

Example: convert 10 THz to kHz:
10 THz = 10 x 1000000000 = 10000000000 kHz

↔ Convert kilohertz to terahertz

terahertz

Definition: A terahertz (symbol: THz) is a unit of frequency equal to one trillion (1,000,000,000,000) hertz (Hz). The hertz, in turn, is the SI unit of frequency, defined as one cycle per second.

History/origin: The terahertz is derived from the hertz, named after the German physicist Heinrich Hertz. The prefix 'tera-' denotes a factor of 10<sup>12</sup>, adhering to the SI system of units.

Current use: Terahertz radiation, or T-rays, is used in emerging technologies such as medical imaging, security screening, and materials science. Terahertz frequencies fill the gap between microwaves and infrared light, offering unique capabilities in sensing and spectroscopy, although widespread applications are still under development.

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.
