Oz. per yard

[ForresterModern]

With a simple conversion to ounces per square inch you know exactly what their fabrics weigh.

Simple for who? I think I need a fifth grader to help me with the math. No wait, I think I got it.

30 grams to an ounce
39.37in per meter = 1550 sq in per sq meter
36" x 60" = 2160 sq in = 1 fabric yard
therefore 1 fabric yard = 1.393 sq meter

so a "fabric yard" of 16oz tartan ought to weigh about 480 grams (or 345 grams per sq meter) give or take, 13 oz tartan ought to weigh 390 grams (or 280 grams per sq meter), 10 oz tartan 300 grams (or 215 grams per sq meter)

I guess that works out as the MM Jura range tartan (I randomly chose Black Isle since I have a kilt in that tartan from them) is listed as 331g/sm and 16 oz (actually more like 15.3 oz tartan if you do the math).

My head hurts. Can I be excused to go find some Advil?
