Frequently asked questions
How do I calculate the cost of running an appliance?
Multiply watts by hours used, divide by 1000 to get kWh, then multiply by your price per kWh.
Where do I find an appliance's wattage?
Look at the label on the back or in the manual. If only volts and amps are given, multiply them to get watts.
