 Looks much nicer!

I have a partial implementation for mass and length units.
You can have a look at it :
https://github.com/mkurdej/units/tree/feature/user-defined-literals
You guess right, there are some problems to solve with output of quantities
created with literals. See lines with FIXME in test/test_literals.cpp

For those who were sceptic about "megagrams" and so on: that was just an
example.
Actually, I implemented tonnes (t), kilotonnes (kt), Gt and so on.
Still, someone could possibly use Mg, Gg for uniformity... (but I haven't
found such a person yet).
