How to Convert Pound per Square Yard to Gram per Square Centimetre
- 1 lb/yd² = 0.05424919596 g/cm²
- 1 g/cm² = 18.43345293 lb/yd²
- Example: convert 15 lb/yd² to g/cm²: 15 lb/yd² = 15 × 0.05424919596 g/cm² = 0.8137379394 g/cm²
Formula
g/cm² = lb/yd² × 0.05424919595981
or g/cm² = lb/yd² ÷ 18.43345292603
Derivation from SI units:
- 1 lb/yd² = 453.59237 g ÷ 0.83612736 m² = 542.4919453 g/m² (exact ratio)
- 1 g/cm² = 10 000 g/m² (1 m² = 10 000 cm²)
- 1 lb/yd² = 542.4919595981 g/m² ÷ 10000 g/m² per g/cm² = 0.05424919595981 g/cm²
Both units are defined exactly, so the factor is exact. Pound per Square Yard definition: pound per square yard; Gram per Square Centimetre definition: gram per square centimetre.
Worked examples
- A reading of 0.75 lb/yd² converts to 0.04068689697 g/cm².
0.75 lb/yd² × 0.05424919596 = 0.04068689697 g/cm² - A value of 2 lb/yd² is 0.1084983919 g/cm².
2 lb/yd² × 0.05424919596 = 0.1084983919 g/cm²
