## Wh to mAh calculation formula

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).

So,

*mAh = 1000 × Wh / V*

*milliamp-hour = 1000 × watt-hour / volt*

**For example:**

*Energy (E) = 5Wh*

*Voltage (V) = 8V*

*Electric charge (Q) = 1000 x 5Wh / 8V = 625mAh*
