Yes, in part. Even without the notion of coherence, "unit", "uno", "einheit" etc. mean "one" *singular*; *not* more than one (plural). Logically, an SI Unit, and its many multiples by SI prefixes can not all be *one*, and also more than one, all at the same time. That would be a contradiction of terms. Gene.
