Precision changes displayed rounding, not calculation accuracy.
ft² = ac × 43560ft² = ac × 43560
Multiply the ac reading by 43560.
1 ac ≈ 43560 ft²
1 × 43560 ≈ 43560
640 ac ≈ 27878400 ft²
640 × 43560 ≈ 27878400
Area factors scale with the square of the length factor. For example, 1 ft = 0.3048 m gives 1 ft² = 0.3048² m² = 0.09290304 m².
