Coulomb

The practical unit of quantity of electricity. It is the quantity pa ed by a current of one ampere intensity in one second. It is equal to 1/10 the C. G. S. electro-magnetic unit of quantity, and to 3,000,000,000 C. G. S. electrostatic units of quantity. It corresponds to the decomposition of.0935 milligrams of water, or to the deposition of 1.11815 milligrams of silver. [Transcriber's note: A coulomb is approximately 6.241E18 electrons. Two point charges of one coulomb each, one meter apart, exerts a force of 900,000 metric tons.]
