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 400 Hz to ms:
  1. Convert to hertz: 400 Hz = 400 Hz
  2. Apply formula: T = 1 / 400 Hz = 0.0025 seconds
  3. Convert to milliseconds: 0.0025 s / 0.001 = 400000 ms

Reverse Conversion

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

  • 400000 ms → f = 1 / 0.0025 s = 400 Hz → 400 Hz
