Understanding Fabric Weights
GSM (grams per square meter) is the standard measure of fabric weight. Higher GSM usually means a heavier/denser fabric.
Conversion Formula
To convert between GSM and ounces per square yard (oz/yd²), use this formula:
1 oz/yd² = 33.9057 GSM
- To find oz/yd²: divide GSM by 33.9057
- To find GSM: multiply oz/yd² by 33.9057
