How to Convert Hertz to Seconds

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 Hz to s:
  1. Convert to hertz: 21 Hz = 21 Hz
  2. Apply formula: T = 1 / 21 Hz = 0.047619 seconds
  3. Result: 21 s

Reverse Conversion

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

  • 21 s → f = 1 / 0.047619 s = 21 Hz → 21 Hz
