How to Convert Hertz to Kilohertz

1 hertz = 0.001 kilohertz

Kilohertz = Hertz × 0.001

Example: 25 Hz × 0.001 = 0.025 kHz

Reverse Conversion

To convert kilohertz back to hertz:

  • Remember, 1 kilohertz equals 1000 hertz.
  • To convert 0.025 kHz to Hz, multiply 0.025 x 1000, resulting in 25 Hz.

25 Hz is also equal to:

  • 1500 revolution per minute
About these units

Hertz: SI unit of frequency; one cycle (or event) per second. Symbol: Hz = s⁻¹

Kilohertz: SI decimal multiple of hertz; 1 kHz = 1,000 Hz = 10³ Hz
