The charge and energy stored in a capacitor can be calculated from the capacitance and voltage across it. The stored energy is essenially the integral of the charge with respect to voltage.

notes
Fill in the capacitance and voltage in the blue input boxes, and the results will appear in the orange boxes.
Note that the expressions for charge and energy are analogs of those for momentum and kinetic energy in Newtonian mechanics.
