How the Energy Bill is Calculated?

The energy consumption and electricity costs are calculated based on the appliance's power, usage hours, and the cost of electricity. Here's the breakdown:

Energy Consumption (kWh):
E(kWh/day) = P(W) × t(h/day) / 1000
Daily Electricity Cost:
Cost($/day) = E(kWh/day) × Cost(cent/kWh) / 100

The formulas help you calculate the energy consumption and electricity cost for your appliance. Make sure to enter the correct values to get accurate results.
