milliamp-hours to watt-hours calculation

The energy E(Wh) in watt-hours is equal to the electric charge Q(mAh) in milliamp-hours times the voltage V(V) in volts (V) divided by 1000:

E(Wh) = Q(mAh) × V(V) / 1000

So watt-hours is equal to milliamp-hours times volts divided by 1000:

watt-hours = milliamp-hours × volts / 1000

or

Wh = mAh × V / 1000
