How to Convert Pound per Square Yard to Gram per Square Metre
- 1 lb/yd² = 542.4919596 g/m²
- 1 g/m² = 0.001843345293 lb/yd²
- Example: convert 1 lb/yd² to g/m²: 1 lb/yd² = 1 × 542.4919596 g/m² = 542.4919596 g/m²
Formula
g/m² = lb/yd² × 542.4919595981
Derivation from SI units:
- 1 lb/yd² = 453.59237 g ÷ 0.83612736 m² = 542.4919453 g/m² (exact ratio)
- Mass in grams of one square metre of fabric (GSM); 1 g/m² = 0.001 kg/m².
Both units are defined exactly, so the factor is exact. Pound per Square Yard definition: pound per square yard; Gram per Square Metre definition: gram per square metre.
