How to Convert Gigahertz 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 400 GHz to ns:
  1. Convert to hertz: 400 GHz = 400 × 1.0e+9 = 4.0e+11 Hz
  2. Apply formula: T = 1 / 4.0e+11 Hz = 2.5e-12 seconds
  3. Convert to nanoseconds: 2.5e-12 s / 1.0e-9 = 400 ns

Reverse Conversion

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

  • 400 ns → f = 1 / 2.5e-12 s = 4.0e+11 Hz → 400 GHz
