Online Calculators since 2009
The Electrical Consumption Calculator calculates the amount of energy used on a list of appliances, and the cost (if the price per kWh (kiloWatt-hours) is entered).
The list below contains an approximate wattage for each item, this will be used for calculation unless the actual wattage has been entered
A specific wattage can be entered in the "Actual" column,
If the wattage is not known it can be calculated by entering figures in the "Volts" and "Amps" boxes (Watts = Volts x Amps)
(Appliances are usually labelled with this information, or may be included in the appliances documentation)
Only items with a value in the "Hours per day" column will be included in the calculation and pdf
Watts = Volts x Amps
1 kW = 1000 Watts
