Calculate Battery Capacity

The capacity of a battery tells how many energy it can provide.

energy = capacity * voltage or work = charge * voltage
E = C * U or W = Q * U

energy: watt-hours (Wh) or kilojoules (kJ)
capacity: milliampere-hours (mAh) or coulombs (C)
voltage: volts (V)

Please enter two values, the third will be calculated.

1 Wh = 3.6 kJ. 1 mAh = 3.6 C. 1Ah = 1000 mAh. The SI-units are kJ and C.

Capacitance (Capacitor)

The capacitance is the ability to store electrical charge. This is stored in an capacitor. Its unit is farad (F) = coulomb (C) / volt (V).

capacitance: farad (F)
charge: coulomb (C)
voltage: volt (V)

Please enter two values, the third will be calculated.





The calculators use . and , als decimal separators.
