Watt-hours to milliamp-hours calculation formula

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

Q(mAh) = 1000 × E(Wh) / V(V)

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

milliamp-hours = 1000 × watt-hours / volts

or

mAh = 1000 × Wh / V
