Common Usage Scenarios
Understanding the Conversion
kWh (kilowatt-hour) measures total energy consumed over time, while Watts measures instantaneous power.
To find average power in watts, divide the total energy (in kWh) by time (in hours) and multiply by 1000.
This calculation helps you understand the average power draw of devices based on their energy consumption.
Key Formulas
Practical Tips
• Check your electricity bill for kWh usage
• Average power = Total kWh ÷ Hours
• Lower wattage = more efficient devices
• Use this to compare appliance efficiency
• Monitor energy consumption patterns
How the Conversion Works
Energy vs Power
Energy (kWh) is the total amount consumed, while power (Watts) is the rate of consumption. Converting between them requires knowing the time period.
The 1000 Factor
Since 1 kWh = 1000 Wh, we multiply by 1000 when converting from kilowatt-hours to watt-hours or watts.
Average Power
The result shows average power over the time period. Actual instantaneous power may vary during operation.
Real-World Examples
Monthly Electric Bill
300 kWh over 720 hours = 417W average power draw
Air Conditioner
12 kWh over 6 hours = 2000W (2kW) average consumption
LED Light Bulb
0.08 kWh over 8 hours = 10W power rating
Gaming Computer
2 kWh over 5 hours = 400W average power usage
Conversion Examples Table
| Energy (kWh) | Time Period | Average Power (W) | Example Device |
|---|---|---|---|
| 0.1 kWh | 10 hours | 10 W | LED Bulb |
| 0.5 kWh | 5 hours | 100 W | Laptop |
| 1.5 kWh | 3 hours | 500 W | Washing Machine |
| 2.4 kWh | 2 hours | 1200 W | Microwave Oven |
| 12 kWh | 6 hours | 2000 W | Air Conditioner |
