Ok - works fine. But how can one generate the Unit of a physical
quantity with a string?
I tried the following, e.g.

using namespace Quantities

...

Concentration(0.01,*(Concentration::AllUnits::unit(unit)))

...

and got the error message:

antity/Variable.h:125: error: incomplete type 'Units::UnitError<true>'
cannot be used to name a scope
