How to Convert Hertz to Terahertz

1 hertz = 1 × 10-12 terahertz

Terahertz = Hertz × 1 × 10-12

Example: 725 Hz × 1 × 10-12 = 7.25 × 10-10 THz

Reverse Conversion

To convert terahertz back to hertz:

  • Remember, 1 terahertz equals 1 × 1012 hertz.
  • To convert 7.25 × 10-10 THz to Hz, multiply 7.25 × 10-10 x 1 × 1012, resulting in 725 Hz.

725 Hz is also equal to:

  • 0.725 kilohertz
  • 0.000725 megahertz
  • 43500 revolution per minute
About these units

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

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

Frequently Asked Questions
