Energy in Watt-hours (Wh) to electric charge in milliamp-hours (mAh) calculator.
Enter the energy in watt-hours (Wh) and voltage in volts (V) and press the Calculate button:
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
