AFAIU, this is a more general design problem.  Switching the language
makes all input (in a broader sense) being interpreted as expression in
that language.  Like, interpreting the built-in unit definitions.

If you reverse your recipe so that Calc builds the unit table before you
switch to Mathematica language mode, the issue doesn't appear.
