We sketch the foundations of classical electrodynamics, in particular the
transition that took place when Einstein, in 1915, succeeded to formulate
general relativity. In 1916 Einstein demonstrated that, with a choice of
suitable variables for the electromagnetic field, it is possible to put
Maxwell's equation into a form that is covariant under general coordinate
transformations. This unfolded, by basic contributions of Kottler, Cartan, van
Dantzig, Schouten & Dorgelo, Toupin & Truesdell, and Post, to what one may call
premetric classical electrodynamics. This framework will be described
shortly. An analysis is given of the physical dimensions involved in
electrodynamics and subsequently the question of units addressed. It will be
pointed out that these results are untouched by the generalization of classical
to quantum electrodynamics (QED). We compare critically our results with those
of L.B. Okun which he had presented at a recent conference.
