Per square yard, not per linear yard
oz/yd² is mass per square yard. Some US mills quote ounces per linear yard of a given width; divide by the width in yards (for example 60 in = 1.667 yd) to get oz/yd².
Fabric Weight unit definitions
- gram per square metre (g/m²)
- Grams per square metre (GSM) is the standard measure of fabric weight: the mass of 1 m² of fabric. T-shirt jersey is about 150–180 GSM, denim 340–475 GSM, spunbond nonwovens 10–100 GSM.
- ounce per square yard (oz/yd²)
- Ounces per square yard is the US fabric weight unit: 1 oz/yd² ≈ 33.906 g/m². Denim is sold as 10–16 oz, shirting as 3–5 oz.
- ounce per square foot (oz/ft²)
- Ounces per square foot is 9 times the oz/yd² figure (1 yd² = 9 ft²). It appears in coatings, laminates, roofing and copper foil weights.
- gram per square centimetre (g/cm²)
- Grams per square centimetre is 10 000 g/m². Laboratory work on small fabric samples, films and membranes often reports areal density this way.
- pound per square yard (lb/yd²)
- Pounds per square yard is 16 oz/yd² and about 542.49 g/m². Heavy industrial fabrics, carpets and geotextiles are sometimes specified this way.
