How to Convert Megahertz to Microseconds

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 420 MHz to µs:
  1. Convert to hertz: 420 MHz = 420 × 1.0e+6 = 4.2e+8 Hz
  2. Apply formula: T = 1 / 4.2e+8 Hz = 2.38095e-9 seconds
  3. Convert to microseconds: 2.38095e-9 s / 1.0e-6 = 420 µs

Reverse Conversion

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

  • 420 µs → f = 1 / 2.38095e-9 s = 4.2e+8 Hz → 420 MHz
