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.

Millihertz (mHz) - Definition and Overview

What is Millihertz?

Millihertz is a measure of frequency equal to one by thousandth(1/1000) of a cycle per second. Millihertz can be abbreviated as mHZ.

Summary

  • Millihertz (mHz) is a unit of frequency in the International System of Units (SI) equal to one thousandth of a hertz (1 mHz = 10^-3 Hz)
  • It is used to measure low frequencies, commonly in applications such as biological rhythms and certain types of electronic signals.

How to Convert Terahertz to Millihertz?

1 Terahertz is equal to 1000000000000000 Millihertz. To convert Terahertz to Millihertz, use this simple formula:

Millihertz = Terahertz x 1000000000000000

So, just multiply the number of Terahertz by 1000000000000000 to get equivalent value in Millihertz.

Example 1:

Convert 5 Terahertz to Millihertz
5 x 1000000000000000 = 5000000000000000 Millihertz

Example 2:

Convert 7.5 Terahertz to Millihertz
7.5 x 1000000000000000 = 7500000000000000 Millihertz
