How to Convert Terahertz to Nanoseconds

Frequency and period are inversely related. The formula is: T = 1 / f, where T is the period and f is the frequency.

Conversion Steps

  • The formula is: Period = 1 / Frequency
  • For example, to convert 221 THz to ns:
  1. Convert to hertz: 221 THz = 221 × 1.0e+12 = 2.21e+14 Hz
  2. Apply formula: T = 1 / 2.21e+14 Hz = 4.52489e-15 seconds
  3. Convert to nanoseconds: 4.52489e-15 s / 1.0e-9 = 0.221 ns

Reverse Conversion

To convert nanoseconds back to terahertz, use f = 1 / T:

  • 0.221 ns → f = 1 / 4.52489e-15 s = 2.21e+14 Hz → 221 THz
