    divide 18.7mm by 25.4 (mm per inch) = .736in

    Josh Madison's free download, above, is the best simple app-purpose conversion program I have ever seen.

    The English who started this bloody system has walked away from it, we, the Americans still stuck with it.

    Bore diameters

    18.3mm = .720 inch

    18.4mm = .724 inch

    18.5mm = .728 inch

    18.6mm = .732 inch

    18.7mm = .736 inch
