How to Convert Ounce per Square Yard to Ounce per Square Foot
- 1 oz/yd² = 0.1111111111 oz/ft²
- 1 oz/ft² = 9 oz/yd²
- Example: convert 15 oz/yd² to oz/ft²: 15 oz/yd² = 15 × 0.1111111111 oz/ft² = 1.666666667 oz/ft²
Formula
oz/ft² = oz/yd² × 0.1111111111111
or oz/ft² = oz/yd² ÷ 9
Derivation from SI units:
- 1 oz/yd² = 28.349523125 g ÷ 0.83612736 m² = 33.90574658 g/m² (exact ratio)
- 1 oz/ft² = 28.349523125 g ÷ 0.09290304 m² = 305.1517192 g/m² (exact ratio)
- 1 oz/yd² = 33.90574747488 g/m² ÷ 305.1517272739 g/m² per oz/ft² = 0.1111111111111 oz/ft²
Both units are defined exactly, so the factor is exact. Ounce per Square Yard definition: ounce per square yard; Ounce per Square Foot definition: ounce per square foot.
Worked examples
- A reading of 5 oz/yd² converts to 0.5555555556 oz/ft².
5 oz/yd² × 0.1111111111 = 0.5555555556 oz/ft² - A value of 10 oz/yd² is 1.111111111 oz/ft².
10 oz/yd² × 0.1111111111 = 1.111111111 oz/ft²
