Kilowatt (kW) to Joule per second (J/s) Conversion

A clear guide to converting Kilowatt into Joule. Includes numeric examples, formulas, and a breakdown of where this conversion appears in science, engineering, and daily applications.

Conversion Formula

Joule = Kilowatt × 1000

To convert Kilowatt (kW) to Joule per second (J/s), multiply the value by 1000. This factor is obtained by comparing their exact meter definitions.

Worked Example

Convert 1 kW to J/s.

  • Step 1: Write the formula: J/s = kW × 1000
  • Step 2: Substitute: 1 × 1000
  • Step 3: Result: 1000 J/s
So, 1 kW = 1000 J/s.
