One of the most widely read posts on this blog is on the topic of screw sizes. If you don't recall it word for word, it is worth re-reading it now. It is now obvious to me that the correct formula is
diameter =
where N is the number of the screw. This is rigged so that a #1 screw is 1/16 inch, and #5 is 1/8 inch. And amazingly, a #10 comes out to 3/16 inch. Incredible. So in a nutshell, we start at 0 being 1/16 and go up by 1/16 for each 5 numbers.
