A comprehensive unit conversion program.
With ConvertAll, you can combine the units any way you want. If you want to convert from inches per decade, that's fine. Or from meter-pounds. Or from cubic nautical miles. The units don't have to make sense to anyone else.

Comments and Reviews
ConvertAll does unit conversions of all sorts (current, historical, obscure, you name it) in a simple clean interface. I've been using this for years on my pc, now if only someone would write an android app along similar lines.
multiplatform, opensource, and allows flexible unit combinations (e.g. "inches per decade")
On Linux this is great. Just about anything you want to convert from and to, and things you really wouldn’t want to like teaspoons to kilometers. But, if that is what you want, you are free to do it. No limitations.
