Using Welder's How do welder's glass shades translate to stops when used as an ND filter?

I've been inspired by this to try using Welder's glass as an ND filter.

For welders' glass, they use values of "shade" from about 4 up to 11 or so. I know 11 is really dark. Does anybody know if there is some sort of a formula to use to calculate how many f-stops a shade 10 filter would be, for example.?
