Wh to mAh calculator

Enter the energy in watt-hours (Wh), voltage in volts (V), then press the Calculate button to get the result in milliamp-hours (mAh).

Wh to mAh calculation

Milliampere-Hours: 0

Q(mAh) = 1000 × E(Wh) / V(V)

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