電気 charge in milliamp-hours (mAh) to energy in Watt-hours (Wh) 計算機.
Enter the 電気 charge in milliamp-hours (mAh) and voltage in volts (V) and press the 計算 button:
The energy E(Wh) in watt-hours is equal to the 電気 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
