I, and most in my specific profession, use US conventional measurement systems (feet, pounds/tons, and acres), but scales that are in tenths of inches, or tenths and hundreths of feet, instead of 1/16th and so forth. It drives my construction friends crazy when they use one of my scales, and they really can't understand why my tape only has 10 inches in a foot or 10 1/16ths in an inch. (LOL). Of course I keep one of those tapes around also.
