Metric vs American wire sizes

[Richard Moody]

Here are some additions to the wire size chart posted earlier  the
differences have been added. It would be interesting to see what the mm
readings are on the metric sizes so one can get an idea of how they are
increasing.  

A difference of .0005 is roughly 5 lbs.   likewise .001 is 10 lbs.   easy
to remember. 

I hope this gets put up with the columns intact...
