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 9.0021 × 107 THz to ns:
  1. Convert to hertz: 9.0021e+7 THz = 9.0021e+7 × 1.0e+12 = 9.0021e+19 Hz
  2. Apply formula: T = 1 / 9.0021e+19 Hz = 1.11085e-20 seconds
  3. Convert to nanoseconds: 1.11085e-20 s / 1.0e-9 = 90021 ns

Reverse Conversion

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

  • 90021 ns → f = 1 / 1.11085e-20 s = 9.0021e+19 Hz → 9.0021e+7 THz
