This tool helps you estimate your monthly electricity consumption based on your household appliances and usage patterns.
KWh Estimator
This KWh estimator allows you to calculate the total kilowatt-hours (kWh) consumed by an appliance over a specified period. This can help you better understand your energy usage and manage your electricity bill. Simply fill in the fields and click on “Calculate” to get the result.
How to Use
- Enter the number of days you want to calculate the energy usage for.
- Enter the power consumption of the appliance in watts (W). You can usually find this information on the appliance label or in the user manual.
- Enter the number of hours per day that the appliance is used.
- Click the “Calculate” button to see the total kWh consumed over the specified period.
How it Calculates
The calculator multiplies the power consumption of the appliance (in watts) by the number of hours used per day and the number of days. This gives the total energy used in watt-hours. To convert watt-hours to kilowatt-hours, it divides the total by 1000 (since 1 kWh = 1000 Wh). The formula is:
Total kWh = (Power Consumption (W) x Hours per Day x Number of Days) / 1000
Limitations
This calculator provides an estimate based on the information you provide. Actual energy consumption can vary due to factors such as appliance efficiency, variations in power consumption, and other external factors. It does not account for standby power usage or energy losses in the system.
