Convert units, organize your code, and a year from now when you look over your old scripts, instantly recognize what units are associated with variables, before and after conversion. Other converters are available (acknowledged below), but the functions in this bundle were designed to be simpler, more comprehensive, and more intuitive. Please alert me if you find any errors.
