Can anybody derivation formula of specific capacitance by cyclic voltammetry.

(Cp=A/(2(V2-V1)×m×k)

Where Cp is the specific capacitance in F/g. A is the area inside the CV curve having unit AV. m is the mass of active material. K is the scan rate of CV in volts per second and V2-V1 is the potential window of CV (Total voltage range).
