Kilowatt (kW) to Kilowatt-Hour (kWh) Calculator
Calculate energy consumption by converting power (kW) and time to kilowatt-hours (kWh).
Energy Consumption:
1 kWh
Understanding Kilowatt-Hours (kWh)
A kilowatt-hour (kWh) is a unit of energy equal to one kilowatt of power sustained for one hour. It's commonly used to measure electrical energy consumption in homes and businesses.
How to Calculate kWh
To calculate kilowatt-hours, multiply the power in kilowatts (kW) by the time in hours:
Energy (kWh) = Power (kW) × Time (hours)
Common Examples
- A 2 kW heater running for 3 hours consumes 6 kWh
- A 0.1 kW (100W) light bulb running for 10 hours uses 1 kWh
- A 1.5 kW air conditioner running for 8 hours consumes 12 kWh
