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 21 GHz to ns:
  1. Convert to hertz: 21 GHz = 21 × 1.0e+9 = 2.1e+10 Hz
  2. Apply formula: T = 1 / 2.1e+10 Hz = 4.7619e-11 seconds
  3. Convert to nanoseconds: 4.7619e-11 s / 1.0e-9 = 21 ns

Reverse Conversion

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

  • 21 ns → f = 1 / 4.7619e-11 s = 2.1e+10 Hz → 21 GHz
