A clarification about the calculation of fabric weight: I don't know what system was used in the past, but I believe the standard today is oz. per sq. yard or gram per sq. metre. (The ISO standard is "gsm", g/m^2) In older sources I see weights referred to in oz or gram per running metre (i.e. one yard of double width fabric.)
I believe the weight per running length was the standard method in the past. I've seen both running weight and weight per yard^2 or meter^2 used with modern fabric.
Another thing I've noticed is various sources cite conversion from grams to ounces different. For example, Holland & Sherry's "intercity" range, which I am a fan of for modern business suits I wear to work, is listed as 370 g or 12 oz, but elsewhere Ive seen 340 g listed as converting to 12 oz. Perhaps, this inconsistency relates to some cloth merchants using running length for standard measurement weight and the ISO standard for metric?
