How to Convert Terahertz to Hertz

1 terahertz = 1 × 1012 hertz

Hertz = Terahertz × 1 × 1012

Example: 89 THz × 1 × 1012 = 8.9 × 1013 Hz

Reverse Conversion

To convert hertz back to terahertz:

  • Remember, 1 hertz equals 1 × 10-12 terahertz.
  • To convert 8.9 × 1013 Hz to THz, multiply 8.9 × 1013 x 1 × 10-12, resulting in 89 THz.

89 THz is also equal to:

  • 8.9 × 107 megahertz
  • 89000 gigahertz
About these units

Terahertz: SI decimal multiple of hertz; 1 THz = 10¹² Hz

Hertz: SI unit of frequency; one cycle (or event) per second. Symbol: Hz = s⁻¹
