Watt-hour

An off-system unit of energy, work. It is usually used when measuring work, electric current energy.Watt-houris equal to the work performed by an electric current with a power of 1Tuewithin 1 hour.

To determine the power in watt-hours, you need to multiply the voltage by the amperage. Let's give an example, a 3 volt battery gives out 2ampereper hour, i.e. it has a capacity of 6Tue-h. If the current is indicated in milliamps per hour, multiply it by volts and divide by 1000.
