How to Convert Acre to Square Yard
- 1 ac = 4840 yd²
- 1 yd² = 0.0002066115702 ac
- Example: convert 15 ac to yd²: 15 ac = 15 × 4840 yd² = 72600 yd²
Formula
yd² = ac × 4840
Derivation from SI units:
- 1 acre = 43 560 ft² = 4 046.856 422 4 m² (international foot; the US survey foot was retired at the end of 2022)
- 1 yd² = (0.9144 m)² = 0.83612736 m² = 9 ft²
- 1 ac = 4046.8564224 m² ÷ 0.83612736 m² per yd² = 4840 yd²
Both units are defined exactly, so the factor is exact. Acre definition: acre; Square Yard definition: square yard.
Worked examples
- A reading of 2 ac converts to 9680 yd².
2 ac × 4840 = 9680 yd² - A value of 20 ac is 96800 yd².
20 ac × 4840 = 96800 yd²
