how to convert fabric weight from oz to gsm
When we describe the weight of denim and other fabrics, we usually use ounces or grams.
gsm means grams per square meter; ounces means weight per square yard. 1 ounce = 28.3 grams.
How about converting oz to gsm?
For example, 10oz=28.3g/oz×10oz=283g (1 square yard), 1 square yard=0.9144m×0.9144m=0.836㎡, so 10oz=283g/0.836㎡=338.5g/㎡(gsm).
100gsm=100×0.836÷28.3=2.95 ounces.
