How to Convert Megahertz 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 MHz to ns:
  1. Convert to hertz: 221 MHz = 221 × 1.0e+6 = 2.21e+8 Hz
  2. Apply formula: T = 1 / 2.21e+8 Hz = 4.52489e-9 seconds
  3. Convert to nanoseconds: 4.52489e-9 s / 1.0e-9 = 221000 ns

Reverse Conversion

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

  • 221000 ns → f = 1 / 4.52489e-9 s = 2.21e+8 Hz → 221 MHz
