note that inch fractions have a hard time keeping up with their decimal and mm counterparts, at least in our ‘real world’ applications such as bead diameters. some times we just have to round off and make do with what we can get…
i restrained the chart size above to match the most common sizes for our fly fishing purposes, should you want more click the pic.
