Just out of curiosity, how are the American ring sizes defined? Because I think the European is simple the diameter of the ring in millimeters (number 12 ring size = 12mm). Or at least this is the way the Finnish ring sizes work. Hmm, I could almost bet there is some EU directive that defines how ring sizes should be defined in all the countries of the European Union. Damn bureaucrats! *g*

the formulae are, according to one site, (http://www.jewellerycatalogue.co.uk/ring-sizes.htm)

To calculate:

American size= (diameter-11.54)/(0.83)
Japanese size= (diameter-12.67)*3
European size= circumference-40
