Watt-hours to the milliamp-hours calculation formula

Energy in Watt-hours (Wh) to electric charge in milliamp-hours (mAh) calculator.

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

mAh = 1000 × Wh / V
