## How to Convert Terahertz to Hertz

To convert a terahertz measurement to a hertz measurement, multiply the frequency by the conversion ratio.

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

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

**For example,**here's how to convert 5 terahertz to hertz using the formula above.

### How Many Hertz are in a Terahertz?

There are **1,000,000,000,000** hertz in a terahertz, which is why we use this value in the formula above.

1 THz = 1,000,000,000,000 Hz

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

## 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 10^{12}. Terahertz can be abbreviated as *THz*; for example, 1 terahertz can be written as 1 THz.

## Hertz

Hertz is formally defined as the frequency equalling 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 = CyclesTime_{s}
