As I have mentioned before, units and dimensions are part of a
larger topic, namely scaling. (Every dimensional argument is
also a scaling argument, but not vice versa: there is such a
thing as non-dimensional scaling, but we don't need to get into
that just now.)
Scaling laws have been part of physics since Day One of modern
science (1638) ... and are still important:

Scaling is not mentioned on the typical syllabus, but IMHO it
should be taught anyway. It is *easier* than most of the stuff
that is on the syllabus, and more age-appropriate ... and it is
treeemendously powerful.
