Hz to THz converter (Hz to THz)
Convert Hz (Hz) to THz (THz) with this free calculator. Type a value, press Convert, and the page applies the same factor shown in the formula below — no rounded shortcut, and nothing is stored on a server.
How to convert Hz to THz
1 hertz (Hz) is equal to 10 ⁻¹² terahertz (THz).
f(THz) = f(Hz) ÷ 1,000,000,000,000
Multiply the frequency in Hz by 0.000000000001:
Example: Convert 1,000,000,000,000 Hz to THz:
f(THz) = 1 THz
What is a Hz?

How this calculator works
The form on this page is a Hz-to-THz converter. After you enter a number, JavaScript multiplies or rearranges it with the published conversion factor and writes the THz result in the output box. The step-by-step panel repeats the arithmetic so you can copy it into homework or a spreadsheet.
