How are electricity units calculated?

You expend 1 unit or 1 Kilowatt-Hour (kWh) of electricity if you use 1000 Watts or 1 Kilowatt of power for 1 hour. 100 x 10 = 1000 Watt-Hour = 1 Kilowatt-Hour (kWH) = 1 unit (on your meter).

How do you calculate cost of 1 kWh?

kWh Explained To calculate the kWh for a specific appliance, multiply the power rating (watts) of the appliance by the amount of time (hrs) you use the appliance and divide by 1000. This 60-watt lightbulb that we used for 90 hours in a month when we were charged $0.09/kWh cost us approximately 50 cents for the month.

How do I calculate my electric meter reading?
