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

## mAh to Wh calculation

Wh: 0

E_{(Wh)} = Q_{(mAh)} × V_{(V)} / 1000

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