How to Convert Hertz to Milliseconds

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 721 Hz to ms:
  1. Convert to hertz: 721 Hz = 721 Hz
  2. Apply formula: T = 1 / 721 Hz = 0.00138696 seconds
  3. Convert to milliseconds: 0.00138696 s / 0.001 = 721000 ms

Reverse Conversion

To convert milliseconds back to hertz, use f = 1 / T:

  • 721000 ms → f = 1 / 0.00138696 s = 721 Hz → 721 Hz
