- 1 THz = 1000000000000 Hz
- 1 × 1000000000000 = 1000000000000 Hz
How to convert terahertz to hertz
1 THz = 1,000,000,000,000 Hz, so multiply by 1,000,000,000,000 to go from terahertz to hertz (cycles per second). Going the other way, 1 Hz = 1 × 10⁻¹² THz.
Hz = THz × 1,000,000,000,000 THz = Hz × 1
Worked example:
1 THz = 1000000000000 Hz 5 × 1000000000000 = 5000000000000 Hz
