How to Convert Kilohertz to Hertz

1 kilohertz = 1000 hertz

Hertz = Kilohertz × 1000

Example: 1390 kHz × 1000 = 1390000 Hz

Reverse Conversion

To convert hertz back to kilohertz:

  • Remember, 1 hertz equals 0.001 kilohertz.
  • To convert 1390000 Hz to kHz, multiply 1390000 x 0.001, resulting in 1390 kHz.

1390 kHz is also equal to:

  • 1.39 megahertz
  • 0.00139 gigahertz
  • 8.34 × 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

Frequently Asked Questions
