Rendered to 6 significant figures.

Formula

Formula
THz = cycles/s × 1e-12

Multiply any value in cycles per second by 1e-12 to obtain the value in terahertz.

Worked example

Convert 1e+12 cycles/s to THz.

  1. 01Start with 1e+12 cycles/s.
  2. 02Multiply by the conversion factor: 1e+12 × 1e-12 = 1 THz.
Result1e+12 cycles/s = 1 THz

FAQ

What is the conversion factor from cycles/s to THz?
1 cycles/s equals 1e-12 THz. To convert, multiply the value in cycles per second by 1e-12.
How do I convert 1 cycles/s to THz?
1 cycles/s = 1e-12 THz. For any value, multiply by 1e-12.
How do I convert THz back to cycles/s?
Divide by the same factor — or equivalently, multiply by 1e+12. So 1 THz = 1e+12 cycles/s.
When would I need to convert cycle per second to terahertz?
Frequency conversions between cycles/s and THz are needed in signal and RF engineering, motor and turbomachinery rotational-speed work, vibration and pulse-rate analysis, and control-loop sample-rate specification. Hz dominates electronics and instrumentation; kHz, MHz and GHz cover audio through microwave; rpm and rps dominate mechanical rotational equipment; cycles per minute, second and hour cover slow industrial cyclic processes. Angular frequency (rad/s) and time-period (Hz ↔ seconds) conversions are NOT included — they require either a 2π factor or a reciprocal relationship.
Is the conversion exact?
The factor shown is precise to at least 7 significant figures. For most process-engineering work this is far better than instrument accuracy. For metrology or trade applications, refer to the relevant national standard (NIST, BIPM, ISO 80000).
