How many acres are there in a square mile?

Explanation:
Understanding area unit conversions. A square mile is a square that is one mile on each side, so its area is 5280 feet times 5280 feet, which equals 27,878,400 square feet. An acre is defined as 43,560 square feet. Dividing the square-mile area by the square feet per acre gives 27,878,400 / 43,560 = 640. So a square mile contains 640 acres. This aligns with common land-area conversions used in surveying and real estate.
