(1873) First report of the Committee for the Selection and Nomenclature of Dynamical and Electrical Units // Report of the 43rd Meeting of the British Association for the Advancement of Science (Bradford, September 1873), pp. 222—225. From p. 223: "The "ohm, « as represented by the original standard coil, is approximately 109 C.G.S. units of resistance ; the „volt“ is approximately 108 C.G.S. units of electromotive force ; and the „farad“ is approximately 1/109 of the C.G.S. unit of capacity.»
