GSM (g/m²)

oz/yd²

Fabric width (cm) — for grams per linear metre

Result

180 GSM = oz/yd²

At 150cm width: g per linear metre ( g per linear yard)

Conversion: 1 oz/yd² = 33.906 g/m². Grams per linear metre = GSM × fabric width (m). These are standard textile-industry formulas — always confirm against your mill's own test report for production decisions.
