Watts to kWh Calculation
The energy E in kilowatt-hours (kWh) is equal to the power P in watts (W), times the time period t in hours (hr) divided by 1000:
E(kWh) = P(W) × t(hr) / 1000
For example: let’s find the kWh of 3000 watts for 2 hours.
E(kWh) = 3000 × 2 / 1000 = 6 kWh
Watts to kWh Conversion Table
Sure, here’s a table showing the conversion of power in watts to kilowatt hours (kWh) for a period of one hour, from 100 watts to 5000 watts:
| Power (Watts) | Energy (kWh) |
|---|---|
| 100 | 0.1 |
| 200 | 0.2 |
| 300 | 0.3 |
| 400 | 0.4 |
| 500 | 0.5 |
| 600 | 0.6 |
| 700 | 0.7 |
| 800 | 0.8 |
| 900 | 0.9 |
| 1000 | 1.0 |
| 1500 | 1.5 |
| 2000 | 2.0 |
| 2500 | 2.5 |
| 3000 | 3.0 |
| 3500 | 3.5 |
