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 420 kHz to ms:
  1. Convert to hertz: 420 kHz = 420 × 1000 = 420000 Hz
  2. Apply formula: T = 1 / 420000 Hz = 2.38095e-6 seconds
  3. Convert to milliseconds: 2.38095e-6 s / 0.001 = 420 ms

Reverse Conversion

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

  • 420 ms → f = 1 / 2.38095e-6 s = 420000 Hz → 420 kHz
