- Jul 17, 2018-

When we describe the weight of a denim fabric and other kind of fabric,we usually use how many oz or how many gsm. 

gsm means grams in per square meter; oz means weight of per square yard. 1 oz=28.3 g.

How about convert oz to gsm?

For example, 10 oz=28.3g/oz×10oz=283g(1 square yard), 1 square yard=0.9144m×0.9144m=0.836 ㎡, so 10 oz=283g/0.836㎡=338.5g/㎡(gsm).

100gsm=100×0.836÷28.3=2.95 oz.
