Minor nit pick: The symbols for SI prefixes, base units and derived units are
case sensitive ("kg" is lowercase).  Otherwise units like mm (millimetre) and
Mm (Megametre) would be indistinguishable.  I think the only exception to this
is the Litre, for which both L and l are acceptable.

But I question the use case for this.  If the whole page was in Italian, and
the author had written "12 chilogrammi" instead of "12kg", then it seems like a
safe assumption that the reader would understand Italian enough to know what
"chilogrammi" means.

This example may be slightly more common, as people outside the US and UK tend
not to be so familiar with imperial and US customary units.  But in contexts
where such conversion matters, it's common for both customary unit and SI unit
to be given together.  I'm not entirely convinced that this is necessary.

There are also many ambiguities for some non-SI units that use the same name
and symbol for different definitions in different contexts or countries.  So
that would have to be taken into account with this proposal.
