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.
