About Square miles and Square centimeters
Square miles (mi²): One mile squared, or 2.59 km²; the standard US unit for large land areas. Common uses: City and county area, state and national park sizes, watersheds, and large geographic features in the US.
Square centimeters (cm²): One centimeter squared, 100 mm² or 1/10,000 of a square meter; convenient unit for small flat areas. Common uses: Surface area of phone screens and other small displays, fabric scraps, and laboratory work.
How the conversion works
Area conversions are derived from length: 1 ft² = (0.3048 m)² = 0.092903 m². 1 acre = 4,046.86 m². 1 hectare = 10,000 m² exactly.
The exact relationship is square centimeters = square miles × 2.58998811e+10, which the calculator at the top of this page applies in both directions. Type into either field and the other updates immediately.
