Easily convert watt-hours (Wh) to watts (W) using this simple calculator. Enter energy in Wh and time in hours to get the power in watts. Fast, accurate, and beginner-friendly.
This Wh to Watts (W) calculator helps convert stored energy into usable power. If you know how much energy a battery or device has (in watt-hours) and for how long it will deliver that energy (in hours), this tool will calculate the average power output in watts. Great for evaluating battery usage, solar panels, and appliances.
Example: 600 Wh used over 2 hours = 600 ÷ 2 = 300 W
Use this free Wh to Watts calculator to convert energy into power. Just enter the energy in watt-hours and the duration in hours to get the result in watts (W). Perfect for battery calculations, electrical systems, and academic use.
| Watt-hours (Wh) | Time (h) | Power (W) |
|---|---|---|
| 500 | 2 | 250 |
| 1200 | 4 | 300 |
