Converting milliamp-hours (mAh) to watt-hours (Wh) is essential for understanding battery energy capacity. The formula to convert mAh to Wh is:

Energy (Wh)=Charge (mAh)×Voltage (V)1000\text{Energy (Wh)} = \frac{\text{Charge (mAh)} \times \text{Voltage (V)}}{1000}

For example, a battery with a capacity of 2000 mAh and a voltage of 3.7 V has an energy capacity of:

2000 mAh×3.7 V1000=7.4 Wh\frac{2000 \, \text{mAh} \times 3.7 \, \text{V}}{1000} = 7.4 \, \text{Wh}

This means the battery can deliver 7.4 watt-hours of energy. Understanding this conversion is crucial for comparing battery capacities across devices and ensuring optimal energy management. citeturn0search0
