Units information array. Units are grouped into measuring systems (English, Metric), and are assigned an integer representing the conversion factor between that unit and the smallest unit in the system. Numeric indexes are actually magical constants that encode conversion data from one system to the next, with a O(n^2) constraint on memory (this is generally not a problem, since the number of measuring systems is small.) |
