Please comment! I agree. The basic language capability of units should not declare any particular set of units. The SI_Units package proposed can be useful, but also terribly limiting. The chosen units would be inappropriate for calculations dealing with submolecular physics, or astronomy. Neither of these fields should be systematically ignored by Ada.
