mAh to Wh Calculator

Enter Electric Charge (mAh): Enter Voltage (V):

 

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

or

Wh = mAh × V / 1000
