Example of Wh to mAh Calculations

To convert watt-hours (Wh) to milliampere-hours (mAh). you need to know the voltage (V) of the battery. The formula to convert Wh to mAh is:

mAh=Wh×1000/Volts

Assuming a common voltage of 3.7V, which is typical for lithium-ion batteries.

Below is a table showing the conversion of various Wh values to mAh. sorted from smallest to largest. assuming a voltage of 3.7V.

Wh	Voltage (V)	mAh	Wh	Voltage (V)	mAh
1.00	3.70	270.27	18.50	3.70	5000.00
22.20	3.70	6000.00	29.60	3.70	8000.00
37.00	3.70	10000.00	40.00	3.70	10810.81

To convert 1 Wh to mAh at 3.7V:

mAh=1×1000/3.7≈270.27 mAh

To convert 100 Wh to mAh at 3.7V:

mAh=100×1000/3.7≈27027.03 mAh

To convert 160 Wh to mAh at 3.7V:

mAh=160×1000/3.7≈43243.24 mAh
