These are some javascript utilities that I either use at work or sometimes just to figure out if I could code them up or not.

Some of them have been heavily tested ( like the microwave ones ) and others haven't. If they work for you then great =). Mostly they are just to avoid having to write out rough manual calculations on a whiteboard all the time. If you find a bug I'd love to hear about it, but I can't promise I have the programming ability to fix everything.
