During my physics lab, we had to calculate a lot of values. Instead of doing it by hand, I figured I'd try out the units-system gem. In the end, we saved ourselves quite a bit of time and errors, my lab partner was pretty happy about it. Only thing I wasn't happy with is displaying significant digits. I wrote a quick dirty "format" method, but wasn't very pleased with it.
This code is unmaintained.
If you do something interesting with it, let me know so I can be happy.
