[MW] You would think so wouldn't you. But I would argue not. Questions of
what units and quantities are can be treated separately from identifying
them (unless you think they do not exist...) (03)

[MW] Yes that would be the right way to set about it. However, whilst
superficially it looks
like it ought to be an easy area to tackle, it is surprisingly ill
understood in practice from
an ontological point of view. (05)
