Units Expert

While working on some other app that required speed units conversion I found that there's no web unit conversion app worthy current JavaScript libraries and tools. So I thought that it could be fun to write one with a real potential of being useful. And here it is :) Wasn't actually so super easy to write, because of huge number of available units. I need to find a proper way to store them with their relations. That also required quite a lot of unit tests to be sure that app will not cause problems or return invalid values. After trying several approaches to units searching, the final, user friendly shape of the app was established. I hope It will be useful and rise productivity for some people. Best Regards, Rafal.
