It's called a "Platon" because it is an elegant name. The standard unit of elegance is an "Astairion" (named in recognition of Fred Astaire) and "Platon" gets a score of 95 out of a possible 100 Astairions. It's short, easy to remember, and ends in "on" like a good unit should. The only reason it doesn't score 100 Astairions is that some people tend to spit when saying any word beginning with a "P".
