Wh To Watts Calculator
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.

Quick Intro: Convert wh to watts
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.
Formula to Convert wh to watts
- Watts (W) = Watt-hours (Wh) ÷ Hours (h)
Example: 600 Wh used over 2 hours = 600 ÷ 2 = 300 W
Wh to watts Calculator Overview
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 |
Frequently Asked Questions - Wh To Watts Calculator:
How do I convert Wh to W?
Use the formula: Watts = Watt-hours ÷ Hours.
What is a watt-hour?
A watt-hour (Wh) is a unit of energy representing one watt for one hour.
Do I need to know the time to calculate watts?
Yes, you need the time (in hours) to convert Wh to W.
Can this be used for batteries?
Yes, it's commonly used to calculate battery discharge power.
Is this tool suitable for solar energy calculations?
Yes, it helps estimate power from stored solar energy.
What’s the difference between Wh and W?
