Cost (in kWh) = Power (in watts) × Time (in hours)
This formula allows you to determine the energy consumption in kilowatt-hours (kWh), which is the standard unit for measuring electricity usage.
How to Use
Using our provided calculator is straightforward. Follow these steps:
- Enter the power consumption in watts in the “Power” field.
- Input the time the device or appliance is in use in hours in the “Time” field.
- Click the “Calculate” button.
The calculator will instantly provide you with the cost of electricity based on your inputs.
Example
Let’s say you have a 1000-watt device (1 kW) that you use for 5 hours a day. To calculate the cost of electricity, enter these values into the calculator:
- Power: 1000 watts
- Time: 5 hours
Click “Calculate,” and the calculator will display the result:
The cost of electricity is 5 kWh.
