How many acres are there in one square mile?

Explanation:
Converting area units from square miles to acres is the key idea. A square mile is 5,280 feet on each side, so its area is 5,280 × 5,280 = 27,878,400 square feet. An acre is defined as 43,560 square feet. Dividing the square-mile area by the square-acre area gives 27,878,400 ÷ 43,560 = 640. So there are 640 acres in a square mile. For quick checks, half a square mile is 320 acres, and two square miles would be 1,280 acres.
