Inspired by this exchange, I decided that I would take a crack at converting X-Acts very useful Java Applet (IVs to PID) to JavaScript, and hopefully kick off a series of useful calculators that can be put on site. Sarenji did all of the user interface work, including input and validation to turn my rough1routines into something usable. So thank you X-Act and Sarenji!
