## How to Convert Hertz to Terahertz

To convert a measurement in hertz to a measurement in terahertz, divide the frequency by the following conversion ratio: 1,000,000,000,000 hertz/terahertz.

Since one terahertz is equal to 1,000,000,000,000 hertz, you can use this simple formula to convert:

terahertz = hertz ÷ 1,000,000,000,000

The frequency in terahertz is equal to the frequency in hertz divided by 1,000,000,000,000.

For example, here's how to convert 5,000,000,000,000 hertz to terahertz using the formula above.
terahertz = (5,000,000,000,000 Hz ÷ 1,000,000,000,000) = 5 THz

## What is a Hertz?

One hertz is formally defined as the frequency of one cycle per second.

The hertz is the SI derived unit for frequency in the metric system. Hertz can be abbreviated as Hz; for example, 1 hertz can be written as 1 Hz.

Frequency in hertz can be expressed using the formula:

Hz = Cycles / Time in Seconds

## What is a Terahertz?

Terahertz is a measure of frequency equal to one trillion cycles per second.

The terahertz is a multiple of the hertz, which is the SI derived unit for frequency. In the metric system, "tera" is the prefix for 1012. Terahertz can be abbreviated as THz; for example, 1 terahertz can be written as 1 THz.
