Terahertz (THz) - Definition and Overview

What is Terahertz?

Terahertz is a measure of frequency equal to one trillion cycles per second. Terahertz can be abbreviated as THz.

Summary

  • Terahertz (THz) is a unit of frequency in the International System of Units (SI) equal to one trillion hertz (1 THz = 10^12 Hz)
  • It is used in advanced scientific research and applications such as spectroscopy, imaging, and communications where extremely high frequencies are required.

Hertz (Hz) - Definition and Overview

What is Hertz?

Hertz is defined as the frequency equalling one cycle per second. The hertz is the SI derived unit for frequency in the metric system. Hertz can be abbreviated as Hz.

Summary

  • Hertz (Hz) is the standard unit of frequency in the International System of Units (SI), defined as one cycle per second
  • It is widely used across various fields including physics, engineering, and music to measure the frequency of periodic phenomena such as sound waves, electromagnetic waves, and mechanical vibrations.

How to Convert Terahertz to Hertz?

1 Terahertz is equal to 1000000000000 Hertz. To convert Terahertz to Hertz, use this simple formula:

Hertz = Terahertz x 1000000000000

So, just multiply the number of Terahertz by 1000000000000 to get equivalent value in Hertz.

Example 1:

Convert 5 Terahertz to Hertz
5 x 1000000000000 = 5000000000000 Hertz

Example 2:

Convert 7.5 Terahertz to Hertz
7.5 x 1000000000000 = 7500000000000 Hertz
