I edited a question and changed "mils" to "mm", though that may not have actually been the unit the author intended. Do we have a policy on this? All my metric friends say "mils" to refer to "mm", while American manufacturers say "mils" to mean thousandths of an inch. Modern engineers call this unit "thou", which in unambiguous.
Do we have a policy on not using ambiguous units, and if they should be changed to the more modern units when encountered? Also, I have no idea which unit was originally intended, as 2 mm plastic is really thick but 2 thou plastic is incredibly thin (as latex gloves are 5-8 thou).
