Converting square miles to acres is a one-step exercise in unit logic. Because an acre is smaller, each square mile contains exactly 640 acres. So multiply sqmi by 640 to get acres, to go back, divide by 640. This ratio keeps land surveys and valuations consistent'a reliable rule for planners too.
Square mile is a large imperial unit of area used to describe cities, counties, and natural reserves. Written sq mile or mi2, it equals the area of a square one mile on each side and serves as a handy bridge between geography and measurement.
Key anchors: 1 mi2 = 640 acres = 27,878,400 ft2 ≈ 2.58999 km2. Because it scales cleanly, planners and analysts use square miles to compare densities, map growth, and summarize vast landscapes clearly. It also powers per-square-mile metrics such as population density.
