Default Confusion over Circle of Confusion

I grabbed one of the many depth of field calculators to play with, and realized that I didn't know what to do with it. I have a camera with a 1.5 crop factor. Is such a calculator applicable to my camera? If so, what would I use, the actual lens focal distance, the crop-factor-adjusted focal distance, or something else? TIA
