How to Convert Kilohertz 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 21 kHz to ms:
  1. Convert to hertz: 21 kHz = 21 × 1000 = 21000 Hz
  2. Apply formula: T = 1 / 21000 Hz = 4.7619e-5 seconds
  3. Convert to milliseconds: 4.7619e-5 s / 0.001 = 21 ms

Reverse Conversion

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

  • 21 ms → f = 1 / 4.7619e-5 s = 21000 Hz → 21 kHz
