The capacitance of a body is defined as the ratio of charge Q to voltage V on the body,
Although most people trained in the MKS system of units find it hard to believe, the cgs unit of
capacitance is the centimeter (Bekefi and Barrett 1987, p. 654; Jackson 1998, p. 783; Purcell 1985). The
MKS unit is the farad (F), defined to be 1 F  1 C V-1, where C is a Coulomb and V is a volt. 1 F =
 cm.
