How to Convert Ounce per Square Foot to Gram per Square Centimetre
- 1 oz/ft² = 0.03051517273 g/cm²
- 1 g/cm² = 32.77058298 oz/ft²
- Example: convert 15 oz/ft² to g/cm²: 15 oz/ft² = 15 × 0.03051517273 g/cm² = 0.4577275909 g/cm²
Formula
g/cm² = oz/ft² × 0.03051517272739
or g/cm² = oz/ft² ÷ 32.7705829796
Derivation from SI units:
- 1 oz/ft² = 28.349523125 g ÷ 0.09290304 m² = 305.1517192 g/m² (exact ratio)
- 1 g/cm² = 10 000 g/m² (1 m² = 10 000 cm²)
- 1 oz/ft² = 305.1517272739 g/m² ÷ 10000 g/m² per g/cm² = 0.03051517272739 g/cm²
Both units are defined exactly, so the factor is exact. Ounce per Square Foot definition: ounce per square foot; Gram per Square Centimetre definition: gram per square centimetre.
Worked examples
- A reading of 0.75 oz/ft² converts to 0.02288637955 g/cm².
0.75 oz/ft² × 0.03051517273 = 0.02288637955 g/cm² - A value of 2 oz/ft² is 0.06103034545 g/cm².
2 oz/ft² × 0.03051517273 = 0.06103034545 g/cm²
