Sorry, I couldn't find a definitive answer either, which leads me to think there isn't one. Here's some of my miscellaneous findings:
The online "How Many? A Dictionary of Units of Measurement" by Russ Rowlett and the University of North Carolina at Chapel Hill shows: "year (a or y or yr) " The couple dictionaries I checked showed both "y" and "yr" as abbreviations. - for CAS, a division of the American Chemical Society, the standard is "yr" - on the BIPM site I found one paper that used the abbreviation "yr", but no papers that used "y", for year - SI uses s for second, which works in both French and English. I'd find it hard to believe the French would accept a standard using "y" or "yr" for year. "a" would work for both languages. Reasons not to use y: - The element Yttrium is Y - SI prefixes include Y yotta and y yocto - Graphs have a y-axis David Shatto Los Angeles On Tue, 21 Oct 2003 15:52:55 -0700 "Ma Be" wrote: > Dear colleagues, > > I've tried and tried and tried, but to no avail.
