Terahertz to Hertz Conversion

Type a frequency in terahertz, press Convert, and the same frequency appears in hertz. One terahertz is 1000000000000 hertz, so every result is the value you typed multiplied by that factor.

How to convert terahertz to hertz

Terahertz and hertz both measure frequency; they differ only by a fixed scale factor. Enter your figure in the terahertz field and press Convert to see it in hertz. Use Copy to take the result with you and Clear to start over with a new number.

Because the step upward is multiplication, going the other way is division: one hertz equals 0.000000000001 terahertz, so a frequency written in terahertz is a million million times smaller than the same frequency written in hertz, with the decimal point moving twelve places to the left.

Terahertz to hertz formula

The frequency f in hertz (Hz) equals the frequency f in terahertz (THz) multiplied by 1000000000000:

f(Hz) = f(THz) x 1000000000000

For example, to change 3 terahertz into hertz, multiply 3 by 1000000000000, which gives 3000000000000 Hz. Equivalently, 1 THz = 1000000000000 Hz and 1 Hz = 0.000000000001 THz.

Conversion chart from terahertz to hertz

The chart below lists common terahertz values next to their hertz equivalents, from 0 THz up to 1 THz. Each row is the left-hand figure times 1000000000000, so you can confirm a mental estimate or read off a value without running the calculation yourself.
