How to Convert Gram per Square Metre to Pound per Square Yard
- 1 g/m² = 0.001843345293 lb/yd²
- 1 lb/yd² = 542.4919596 g/m²
- Example: convert 500 g/m² to lb/yd²: 500 g/m² = 500 × 0.001843345293 lb/yd² = 0.9216726463 lb/yd²
Formula
lb/yd² = g/m² × 0.001843345292603
or lb/yd² = g/m² ÷ 542.4919595981
Derivation from SI units:
- Mass in grams of one square metre of fabric (GSM); 1 g/m² = 0.001 kg/m².
- 1 lb/yd² = 453.59237 g ÷ 0.83612736 m² = 542.4919453 g/m² (exact ratio)
Both units are defined exactly, so the factor is exact. Gram per Square Metre definition: gram per square metre; Pound per Square Yard definition: pound per square yard.
Worked examples
- A 500 g/m² industrial fabric weighs 0.9216726463 lb/yd².
500 g/m² × 0.001843345293 = 0.9216726463 lb/yd² - A 1000 g/m² carpet weighs 1.843345293 lb/yd².
1000 g/m² × 0.001843345293 = 1.843345293 lb/yd²
