Table 8 is online at: http://www.bipm.org/en/si/si_brochure/chapter4/4-1.html The BIPM says table 8 are units whose "use is not recommended" and "These units should be defined in relation to the SI in every document in which they are used.". Until 1996, table 8 used to be called units "to be avoided". >Does inclusion of the bar in this list make it >appropriate to say, millibars is metric¹? No it does not. The best BIPM definition of 'metric' that I have found is in the BIPM brochure. It says "the International System of Units (SI), which is the modern form of the metric system". Note that it uses the definite article. Thus since 1960 'metric system' and 'SI' are synonyms. After 4 decades, the word modern is superfluous. The bar is not SI and therefore not metric. It *was* metric but is not now. __________________________________ Yahoo! for Good - Make a difference this year. http://brand.yahoo.com/cybergivingweek2005/
