How to convert Wh to mAh
How to convert watt-hour (Wh) to milliampere-hour (mAh).
Watt-hour to milliampere-hour calculation formula
The electric charge Q(mAh) in milliampere-hours (mAh) is equal to the energy E(Wh) in watt-hours (Wh) times 1000 divided by the voltage V(V) in volts (V):
Q(mAh) = E(Wh) × 1000 / V(V)
So milliamp-hour is equal to watt-hour times 1000 divided by volts:
milliamp-hour = watt-hour × 1000 / V
or
mAh = Wh × 1000 / V
Example
Find the electric charge in milliamp-hour when the energy consumption is 3 watt-hour and the voltage is 5 volts.
The electric charge Q is equal to 3 watt-hour times 1000, divided by 5 volts:
Q = 3Wh × 1000 / 5V = 600mAh
