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 electro-motive force; and the ‘farad’ is approximately 1/109 of the C.G.S. unit of capacity.” - The Committee for the Selection and Nomenclature of Dynamical and Electrical Units, 1873
This was a watershed moment for civilization. Never could a manufacturer take a specification and be assured that a comparable piece could be found, tested, and verified before running it through a mountain range or putting it miles below the ocean. 1881 - The first international electrical congress Even though the British Association for the Advancement of Science mostly completed their work for a standard unit of electrical resistance, some nations did not accept the standard at first. It took a concerted effort to create an international consensus. In 1881 the world’s greatest minds converged on Paris for the First International Electrical Congress. From the fifteenth of September through the fifth of October, a jury of one hundred forty-four representatives from fifteen different countries came together to standardize electrical units for measurement, but also discuss business at hand concerning machines, motors, weights, coils, electrical lamps, sewing machines, etc.

The International Electrical Congresses in the late 19th and early 20th centuries established electrical standards that drove the Second Industrial Revolution's growth and innovation. These meetings brought together the brightest minds in electrical engineering and were instrumental in propelling rapid technological advancements and industrial expansion.
The news reached London the last week of September and was first published in the London Week News, where it was said: “the passing of these resolutions by the Congress today unanimously, and their acceptance as international decisions by the most distinguished assemblage of physicists which have ever met together in the world’s history, i s quite as remarkable as it is satisfactory.”
An immortal legacy Two hundred years after he first published ‘The Galvanic Circuit Investigated Mathematically,’ Georg Ohm is still in the back pocket of every engineer and technician worldwide. Latimer Clark honored Ohm by proposing a unit of measure for him, immortalizing his work in ways that very few people ever could be. This year, on Ohm’s Day, while you’re celebrating with your friends and loved ones, let us not forget the people like Sir William Thomson (Lord Kelvin), James Maxwell, Sir Charles Wheatstone, Latimer Clark, and Sir Charles Bright, who lifted him above the pantheon of the giants who made our understanding of the movement of electrons possible.
Latimer Clark reads his proposal in Manchester.
