Watt (W) to Joule per second (J/s) Conversion

Watt to Joule conversion explained with exact factors, step-by-step examples, and situations where this conversion is commonly used.

Conversion Formula

Joule = Watt × 1

To convert Watt (W) to Joule per second (J/s), multiply the value by 1. This factor is obtained by comparing their exact meter definitions.

Worked Example

Convert 1 W to J/s.

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