This physics video provides a basic introduction into the kilowatt hour unit. It's a unit of energy and not power. Kw or kilowatt is the unit of power. Energy is power multiplied by time. The kilowatt (unit of power) multiplied by hours (unit of time) will you give you a unit of energy which is the Kwh. 1 Kwh is equal to 3.6 Mega Joules. This video explains how to calculate the electric utility bill of running a 60W light bulb and a 3.5kW air conditioner unit continuously for 1 month at a cost of $0.13 per kWh.
