About this tool
Area units are the square of their length unit, which is why the factors look surprising: one square metre is about 10.76 square feet, not 3.28, because the length factor is squared.
Land uses its own units. A hectare is a clean 10,000 m² — a square 100 m on each side. An acre is historical: 4,046.8564224 m², originally the area one ox team could plough in a day, and there are about 2.47 acres to a hectare.
