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 420 Hz to ms:
  1. Convert to hertz: 420 Hz = 420 Hz
  2. Apply formula: T = 1 / 420 Hz = 0.00238095 seconds
  3. Convert to milliseconds: 0.00238095 s / 0.001 = 420000 ms

Reverse Conversion

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

  • 420000 ms → f = 1 / 0.00238095 s = 420 Hz → 420 Hz
