OK. Let us forget about the past and only deal with current SI and current metric. > "Metric-system" is incorrect. The term is never hyphenated. OK. I must have put that in accidentally because it helps with web search engines when searching for adjacent words. > In general, though, metric does not necessarily mean SI. Erg, dyne, gauss, > oersted, curie, and so on are all metric, but they are not SI. > > Therefore, "non-SI" does not mean "non-metric." So I understand that you mean that SI is a subset of metric. Where do you get this definition from? What makes something metric and non-metric?
