How to Convert Kilohertz to Hertz

1 kilohertz = 1000 hertz

Hertz = Kilohertz × 1000

Example: 674 kHz × 1000 = 674000 Hz

Reverse Conversion

To convert hertz back to kilohertz:

  • Remember, 1 hertz equals 0.001 kilohertz.
  • To convert 674000 Hz to kHz, multiply 674000 x 0.001, resulting in 674 kHz.

674 kHz is also equal to:

  • 0.674 megahertz
  • 0.000674 gigahertz
  • 4.044 × 107 revolution per minute
About these units

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

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