From a glance at the list, that indeed appears to be the case (the classes being “length”, “mass”, “length squared”, “length over time”, etc.). > (It also follows that for this particular constraint, the checker should in fact //not// apply unit conversions, but we don’t have a way to express that in the constraint statement yet.) We could create a class that represented a "convertible unit in Wikidata", of which the corresponding Items (units) were instances. However, I'm not sure if this is possible right now or not at the implementation level because I also don't know to what extent there are hardcoded classes of units in WikibaseQualityConstraints or whether it's possible to create new classes and immediately use them in "allowed units" constraints.
