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 21 MHz to ns:
  1. Convert to hertz: 21 MHz = 21 × 1.0e+6 = 2.1e+7 Hz
  2. Apply formula: T = 1 / 2.1e+7 Hz = 4.7619e-8 seconds
  3. Convert to nanoseconds: 4.7619e-8 s / 1.0e-9 = 21000 ns

Reverse Conversion

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

  • 21000 ns → f = 1 / 4.7619e-8 s = 2.1e+7 Hz → 21 MHz
