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.

Conversion Formula
To convert milliampere-hours to watt-hours, you’ll need to know both the battery’s capacity (in mAh) and its voltage (in V). The formula to perform this conversion is:
Watt-Hour (Wh)=Milliampere-Hour (mAh)×Voltage (V)/1000
Step-by-Step Conversion Process
- Identify the Battery Capacity: Find the battery’s capacity in milliampere-hours (mAh). For example, let’s use a 2,500mAh battery.
- Measure the Voltage: Determine the voltage of the battery. Suppose it is 3.7V.
- Apply the Formula: Plug these values into the formula.
Wh=2,500mAh×3.7V/1000=9.25Wh
So, a 2,500mAh battery at 3.7V has a capacity of 9.25Wh.
