So you don't need to worry about units not matching. There is the Units` package which provides some limited support for units, but I have never used it seriously. I think that not using units explicitly in your program will be the most productive way to work. -- Szabolcs Horvát Mathematica QA site proposal: http://area51.stackexchange.com/proposals/37304
