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