What is the Energy Consumption Calculator?

The Energy Consumption Calculator helps users determine the electrical energy consumed by an appliance and optionally calculates the total cost. By inputting the power rating of the device (in watts) and the duration of use (in hours), the tool computes energy consumption in kilowatt-hours (kWh). If the cost per kWh is provided, it also estimates the total cost of electricity used. This calculator is useful for households, students, and anyone looking to monitor or manage electricity usage.

How to Use:

1. Enter Power (P): Input the power rating of the appliance in watts (W).
2. Enter Time (t): Input the duration the appliance runs in hours.
3. Enter Cost per kWh (optional): Provide the electricity cost per kilowatt-hour in your currency to calculate the total cost.
4. Click “Calculate”: The calculator converts power × time into energy in kWh and multiplies by cost per kWh if provided.
5. View Results: The tool displays the input values, calculated energy consumption, total cost (if applicable), and the formula used.
