Example of mAh to Wh Calculations
To convert milliampere-hours (mAh) to watt-hours (Wh). you need to know the voltage (V) of the battery. The formula to convert mAh to Wh is:
Wh=mAh×Volts/1000
Assuming a common voltage of 3.7V, which is typical for lithium-ion batteries.
Table of mAh to Wh Conversions
Below is a table showing the conversion of various mAh values to Wh. sorted from smallest to largest. assuming a voltage of 3.7V.
| mAh | Voltage (V) | Wh | mAh | Voltage (V) | Wh |
|---|---|---|---|---|---|
| 24000.00 | 3.70 | 88.80 | 25000.00 | 3.70 | 92.50 |
