iLinear conversion using factor 1/1000000000000. Prefer the exact factor over rounded multipliers when precision matters.

How to use

Choose Hz → THz or THz → Hz

Use the tabs to switch direction. Forward mode needs hertz; reverse uses the opposite unit.

Definition: Hertz (Hz) converts to THz using a fixed linear factor. Convert hertz (Hz) to terahertz (THz). Exact factor: 1 THz = 1e12 Hz. Formula THz = Hz ÷ 1e12, worked examples, and a chart.
What it calculates: Value between Hz and THz. Switch direction with the converter tabs.
Inputs: Hertz (Hz) or reverse unit (THz)
Outputs: Converted value in THz or Hz
Formula: THz = Hz × 1/1000000000000 · 1 Hz = 1/1000000000000 THz
