AbleCommerce Shopping Cart Software

There are a lot products that I sell that can benefit from putting certain calculators on the pages. An example would be converting from inches to cm for my international customers. Normally I would do this with a simple JavaScript calculator. The problem I have is that the JavaScript does not work well with the ASP code. Is there an easy way to get around this? If not, would it be hard to code in some simple configurable calculation boxes? This could be a really unique feature for Able. I think it had capabilities beyond that the obvious.
