[edit] SI units
SI units are used in describing soil characteristics relevant to USA soil taxonomy, 1938 USDA soil taxonomy, FAO soil classification, and the World Reference Base for Soil Resources (WRB). This is per established covention for these systems, but if you have a different understanding, please give us a shout here. -- Paleorthid 16:09, 17 June 2006 (UTC)
