Formula & Calculation Steps:
Wh = (mAh × Volts) / 1000
Converting mAh to Wh
Milliampere-hours (mAh) measure electric charge over time, typically used for battery capacity. Watt-hours (Wh) measure electrical energy. To convert between the two, you need to know the battery's operating voltage.
$$ E_{(Wh)} = \frac{Q_{(mAh)} \times V_{(V)}}{1000} $$
Energy in Wh is charge in mAh times voltage in V divided by 1000.
