Then you can use the UN/ECE international standardization of the SI brochure (described in attached), and in schema form at http://www.unece.org/uncefact/codelist/standard/UNECE_MeasurementUnitCommonCode_6.xsd ("Codes for Units of Measure used in International Trade"). You get rid of those 'pesky mu ( µ) for micro' problems, which I'm sure is one of the reasons code lists were invented to begin with -- different languages, fonts, ... And you get a schema. Translation to symbols happens further up the food chain. -A Toby Considine wrote, On 6/15/2011 3:41 PM: There has been much back and forth on the final source for * exactly * the correct si prefixes, and multiple sources Well, at last: http://www.bipm.org/en/si/si_brochure/general.html http://www.bipm.org/utils/common/pdf/si_brochure_8_en.pdf http://www.bipm.org/en/si/si_brochure/ and, in particular, the prefixes…. http://www.bipm.org/en/si/si_brochure/chapter3/prefixes.html Still no publicly accessibly codelist. Of course, there is still that pesky mu ( µ) for micro….
