Electric charge in milliamp-hours (mAh) to energy in Watt-hours (Wh) calculator.
Enter the electric charge in milliamp-hours (mAh) and voltage in volts (V) and press the Calculate button:
The energy E(Wh) in watt-hours is equal to the electric charge Q(mAh) in milliamp-hours times the voltage V(V) in volts (V) divided by 1000:
E(Wh) = Q(mAh) × V(V) / 1000
So watt-hours is equal to milliamp-hours times volts divided by 1000:
watt-hours = milliamp-hours × volts / 1000
or
Wh = mAh × V / 1000
