Joules to kW Calculator
Use this free Joules to kW calculator to convert energy (J) into kilowatts (kW) using time (seconds). Quick and accurate results for physics and electrical power calculations.
Quick Intro: Convert Joules to KW
The Joules to kilowatts calculator helps you convert energy (J) into power (kW) using the formula: kW = (J / t) / 1000. This is useful in both physics and electrical engineering.
Formula to Convert KW to Volts
- kW = (J ÷ t) ÷ 1000
- J = energy in joules, t = time in seconds
Example: 5000 J over 10 sec → (5000 / 10) / 1000 = 0.5 kW
