The link below is to a metrication article published in Standardization News. It addresses the reluctance Americans have for learning the metric "language," the complaints they have for it's "never-ending" changing, and, mainly, the article explains the principles of SI.
This is an older writing, probably not seen by the newer members to this forum, but in any case worth repeating on the Metric Week occasion (the 10/10 date). http://www.astm.org/SNEWS/SEPTEMBER_2001/jakuba_sept01.html Stan Jakuba
