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.
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.
Example: 5000 J over 10 sec → (5000 / 10) / 1000 = 0.5 kW
Easily convert energy in Joules to power in kilowatts using this free calculator. Enter joules and time in seconds to find the equivalent power output.
| Energy (Joules) | Time (Seconds) | Power (kW) |
|---|---|---|
| 1000 | 2 | 0.5 |
| 5000 | 10 | 0.5 |
Use the formula kW = (J ÷ t) ÷ 1000, where J is energy in joules and t is time in seconds.
kW = (J / seconds) / 1000.
