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

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

Conversion Formula

Watt = Joule × 1

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

Worked Example

Convert 1 J/s to W.

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