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

Hertz and terahertz are both units used to measure frequency. Keep reading to learn more about each unit of measure.

What Is a Hertz?

One hertz is formally defined as the frequency of one cycle per second.[1]

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.
