Named after Charles-Augustin de Coulomb, the coulomb is a fundamental unit of electrical charge (represented as C). It is also the SI derived unit of electric charge (represented as Q or q). It may be summarized as the charge transported by a constant current of one ampere over the period of one second.

Though it has the opposite sign (+), the coulomb is equal in magnitude (absolute value) to the charge of about 6.241×1018 electrons. Mathematically: 1 C = 1 A * 1 S.
