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

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).
