GM Steve,

Engage pedant mode.

Well, there's ISO Coarse and ISO fine series metric thread pitches but I agree only one common pitch for each diameter. And what's wrong with Whitworth? It is nice and coarse and so ideal for cast iron :-) Oh, and also Aluminium...

Thread pitch is easy with metric because there is only one standard pitch for
a given diameter, no SAE/UNC/UNF or (God forbid) Whitworth. And as far as I
can tell, metric country pipe threads are in inches.
