How it works
Convert floor space, lot sizes and land areas between metric units (square meters, hectares, square kilometers) and US customary units (square feet, square yards, acres, square miles).
Area factors are the square of the length factor: because 1 ft = 0.3048 m, 1 ft² = 0.3048² = 0.09290304 m². An acre is 43,560 square feet and a hectare is 10,000 square meters, or about 2.47105 acres.
Formula
Result = value × (m² per from-unit) ÷ (m² per to-unit). 1 acre = 4,046.8564224 m².
