I came across the excellent ruby-units package, written by Kevin Olbrich, while working on a Ruby package to analyze Polar S710i heart rate monitor files.

My own units package had a few problems. But, Kevin’s worked out much better, after working with him on test cases and pinpointing performance enhancements.

It supports Kevin’s Uncertain class, like “5 +- 1 meter/sec”.

Go get it: gem install ruby-units
