July 2013 Issue
Mailport: July 2013
I liked the intent of your April 2013 anchor shank article, but I really object to the metric units. What percentage of your readership do you possibly think can relate to newtons, megapascals, etc.? Some day, the U.S. may go metric, but I do not think PS should take the lead on this. Please stop.

We apologize for any irritation the use of metric may have caused. The test was conducted in Australia, using metric equipment. The editor, his brain reeling from spring refit projects, made a foolhardy attempt to again test the readership’s readiness for a metric conversion. This was, as his 10-year-old son would say, “an epic fail.“ In the future, we will convert when feasible, or offer both metric and U.S. Because the conversion from megapascals to pounds per square inch results in nine-digit numbers for anchor steel (1 megapascal = 145 pounds per square inch), and because megapascal is the most common term used for the strength of anchor steel these days, we intend to stick with megapascals, unless we hear an uproar from more readers who insist on pounds per square inch. In the end, the relative numbers are what matter here.
