    They can't even get the wrong units right

    You clearly haven't seen any of my projects.

    And while you are all cheering on the metric system find me a metric thread as fine as teh fine imperial threads and a metric coarse as coarse as the coarse imperial threads. There were sound engineering reasons why Whitworth and others engineered the fasteners they way they did, while the metric system was developed by people who couldn't divide by 12.

    I have a selection of BA taps & dies at home down to (I think) 12BA; the tapping drill for that is a number 60 (1.05mm)

    All standard metric fine threads are finer than BSF, but I fail to see the relevance of any of that anyway...

    By diameter and pitch yes; but the threadform and thread angles are very different.
