mAh to Wh conversion calculator

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:

Enter charge in milliamp-hours: mAh
Enter voltage in volts: V
Energy result in watt-hours: Wh

milliamp-hours to watt-hours calculation

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


Wh = mAh × V / 1000
