I have a German customer who would like to convert the standard; 1 oz., 2 oz. copper on their drawings into the metric system, specifically microns. Does anyone know of a conversion table or just the conversion factor one would use. I'm thinking that say 1 oz./ sq.ft. would become some grams per micron, but have been told it's not that simple. Help!
