Counts?

Does it make sense to define "Counts" ?

For example, in intensity can be described as counts per second. Similarly, for an inductor or helmholtz coil we might have "turns" / meter. Now turns is just syntactic sugar really and could be user defined, it's a counting event.

Or in chemistry we have a notion of a "mole" which is ~6.023x10^23 "atoms/molecules/moeities/etc". For analysis sometimes we care about this type of unit IE: Parts Per Million (ppm).

I understand these aren't SI or MKT units but they are fundamental :). Would really appreciate this consideration. There is a chance this is in here somewhere but I can't figure out how to do it without some pretty hacky stuff.

The issue names no files, tests, or entry points. Start by reviewing the existing unit-definition and extension APIs, then determine whether count-based units, turns, and mole-related quantities can be represented without hacks. Done should mean a concrete, agreed scope and design for supporting these units, with affected tests or documentation identified.
