I am new to SMath, and am wondering how additional units can be added to the built-in list. Like cu ft, or cu yds for volume, US tons, cubic feet per second, etc. Have others added to the built-in units, or is there a quick way to import a library with a broader range of units?
Engineering/Sciences use SI . The most complete unit conversion system I know of: "Katmar" Uconeer 2.4 [freeware]. From there on, built your own missing in Smath.
