How the Area Converter works
Every area unit is defined by a fixed number of square meters, so the converter turns your value into square meters and then into the target unit. Because area is length squared, the conversion factor is the square of the length factor: one foot is 0.3048 m, so one square foot is 0.3048² = 0.092903 m².
Useful reference values: 1 hectare = 10,000 m² ≈ 2.471 acres, 1 acre = 43,560 ft² ≈ 4,046.86 m², and 1 square mile = 640 acres ≈ 2.59 km². These are handy for property listings, floor plans and land measurements.
