Sorry I meant the unnamed numerical constants in equations, rather than the
official named constants like 'g'. I was just used to seeing simple
equations in text books with no numbers in them (just symbols) yet in one of
my books they use imperial units and almost every equation has some
numerical constant in it. On top of that they find it necessary to write
the units needed for every quantity, which I guess have to tie up with the
constant. It just looks messy (and presumably quite hard to remember),
that's all.
