In recent years, more courses in electromagnetism are using the “Système International” (SI) units as opposed to Gaussian-cgs. The confusing notation used to formulate SI with origins in the early 19th century still persists in instruction. This work shows that electromagnetism may be taught relatively painlessly in the units that virtually everyone uses by employing a new presentation that makes the equations nearly as simple as those in the Heaviside–Lorentz system commonly used by theoretical physicists. Introducing a new coupling constant κ and some new notation for the fields, it is possible to dispense with ϵ0 and μ0 and the conceptual framework from which they come. As a result, it is possible achieve much greater clarity, while using all the same symbols and relations as in the extant literature.
