About the Area Converter
Area units are the square of a length unit, so their factors are squared too: one foot is 0.3048 m, so one square foot is 0.3048² = 0.09290304 m².
An acre is 43,560 square feet (4,046.8564224 m²). A hectare is 10,000 m², a square 100 m on each side, and equals about 2.471 acres.
