Fabric Weight Converter — GSM, oz/yd² & oz/linear yard
Convert between fabric weight measurement systems: GSM, ounces per square yard, and ounces per linear yard.
How We Calculate This
Conversion formulas
- GSM to oz/yd²: Divide GSM by 33.906 (the exact factor is 33.9057 = 28.349523 g/oz ÷ 0.83612736 m² per yd²)
- oz/yd² to GSM: Multiply by 33.906
- oz/linear yard to GSM: Requires fabric width. One linear yard at width W cm covers 0.9144 m × (W ÷ 100) m². Convert ounces to grams (× 28.3495), then divide by that area.
