Uh, what relationship between liter and kilogram? You are thinking of
earlier versions of the metric system; SI defines no such relationship.

I think that was Jay's point, Henry . . .

Hardly. He's criticizing SI because this particular relationship doesn't
work in practice, but SI has never claimed it did -- the claimed merits of
SI simply have nothing to do with this strawman argument.

Yes, earlier metric systems did claim such a relationship... but then, his
argument began with the assertion that the English Engineering system of
units -- whichever one that is -- was complete and consistent and should
be considered by itself, independent of the confusion introduced by all
the *other* English systems of units used in engineering. The least he
can do is extend the same courtesy to the metric system.
