How to Calculate Electric Consumption
- 1). Locate the electrical information panel on the appliance. This is a metal label that is physically stamped onto one side of the appliance. This label is required by law to be present on all electrical appliances.
- 2). Locate the required voltage and amperage on the electrical label.
- 3). Multiply the voltage by the amperage. This gives the wattage of the electrical device.
- 4). Divide the resulting product by 1000. This final result is the kilowatt usage of the device. Further, this is the kilowatt-hour electrical usage of the device for every hour the device is in use.
