Converting milliamp hours (mAh) to watt hours (Wh) is a simple calculation. Multiply the milliamp hours by the voltage and divide by 1000 to obtain the watt hours. The formula is: Wh = (mAh * V) / 1000. For example, if you have a 1000 mAh battery with a voltage of 3.7V, the calculation would be (1000 mAh * 3.7V) / 1000 = 3.7 Wh.
