Thanks but I was merely seeking your clarification of what you wrote rather than what is in the brochure. Would I be right in thinking that you meant me to link the two sentences that you wrote and apply the term 'obsolete' (or 'effectively obsolete') to units in tables 9 and 10? That was all I was trying to ascertain, it would help me in my work. >In USMA 22314 Terry states "NIST wrote that it is confusing and >redundant: a) to use the term "SI metric" system because it implies >that there are metric systems other than the International System of >Units (SI)," This is plainly wrong. The term "metric systems" covers >much more than SI. OK. It is a quote from the FTC website. If it is wrong, then either the NIST is wrong or the FTC misquoted them.
