gigahertz [GHz] to terahertz [THz] Converter

Quick Reference

1 gigahertz (GHz) = 0.001 terahertz (THz)

1 terahertz (THz) = 1000 gigahertz (GHz)

How to Convert gigahertz to terahertz

1 GHz = 0.001 THz
1 THz = 1000 GHz

To convert gigahertz to terahertz, divide the value by 1000 (equivalently, multiply by 0.001). To convert terahertz back to gigahertz, multiply by 1000.

Example: convert 10 GHz to THz:
10 GHz = 10 x 0.001 = 0.01 THz

↔ Convert terahertz to gigahertz

gigahertz

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

History/origin: The gigahertz is derived from the hertz, named after the German physicist Heinrich Hertz, who made significant contributions to the understanding of electromagnetic waves. The prefix 'giga-' denotes a factor of 109, adhering to the SI system of units.

Current use: Gigahertz is primarily used to measure the clock speeds of modern computer processors, the frequencies of wireless communication technologies (e.g., 5G cellular networks), and radar systems. It represents very high-frequency signals and operations.

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 1012, 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.
