I like this. Wouldn't it be nice to be able to write
SPEED_OF_LIGHT.unit
-> m / s
(I think this should be easy by subclassing Float).

I also would like to do calculations on units, so that I can write:
s=FwU.new(100,Unit.m)  # shold be shorter, perhaps: s=FwU(100,:m)
t=FwU.new(10,Unit.s)
v=s/t
v       --> 10
v.unit  --> [[Unit.m, 1], [Unit.s, -1]]
# any ideas to do this nicer?
but I don't know this is wort bothering (does anyone really need this?)
