Not entirely true. Yes, it had a rapid conversion. No, it wasn't a British Commonwealth country. South Africa left the Commonwealth in 1961 and rejoined it in 1994. Your own article on the USMA web site says that the conversion took place from 1967 to 1977. Bill Potts, CMS Roseville, CA http://metric1.org [SI Navigator]
