Private: the calculation runs in your browser. Your inputs are not sent to GharGanit.
Rated power can be different from average power while the appliance is running.
Voltage, automatic on-off cycling and equipment condition can change real use.
Use this as a budget estimate. The appliance label, how often it runs and all charges on your tariff determine the real bill.
The result converts electrical input and an average load factor into energy; AC tonnage is not used as a substitute for input watts.
Prefer the model's rated input or BEE annual-energy data and adjust the load factor after observing room temperature, cycling and usage.
Multiplying 1.5 ton by a guessed watts-per-ton value can badly misstate inverter AC consumption.
Energy (kWh) = watts × quantity × hours × days × operating factor ÷ 1,000
