https://doi.org/10.1351/goldbook.I03068
Integral capacitance (per unit area of electrode) is given by $K=\frac{Q}{E- E_{Q=0}}$ where Q is the electric charge (per unit area of electrode), E is the potential of the electrode with respect to a reference electrode, and E Q = 0 is the potential at the point of zero charge.
