When I edit articles for the Rock Garden Quarterly, I try to include both metric and U.S. measurements; this is the standard practice for publications in the United States that expect to have an international readership. Since I'm bad at calculation, I often make mistakes, but proofreader Hans Sauter catches them. I sincerely wish the US would go metric "cold turkey" as Canada did, so we editors wouldn't have to deal with this, but I admit that I don't know, without looking at my bi-scalar thermometer, the Celsius equivalents for temperatures above freezing. I know those below freezing because (a) they're important in gardening and (b) I lived in Alaska, which is near Canada and very concerned with cold temperatures. This pig-headedness is just one more thing that embarrasses some of us hegemonic Americans. Jane McGary
