My reply is those who have posted saying "You don't need to all this
complicated dimensional analysis stuff - just build a units library then
add dimensional analysis on top". I don't believe it can be done that way
round - which I think is what you are saying too. I believe (and have
kept saying) that a units library must incorporate dimensional analysis in
order to be useful. Others didn't appear (to me) to have that view.
Maybe I was confused.
