How to Convert Kilohertz to Microseconds

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 µs:
  1. Convert to hertz: 21 kHz = 21 × 1000 = 21000 Hz
  2. Apply formula: T = 1 / 21000 Hz = 4.7619e-5 seconds
  3. Convert to microseconds: 4.7619e-5 s / 1.0e-6 = 21000 µs

Reverse Conversion

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

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