How the Area Converter works
Area units are converted through the square metre. Because area is two-dimensional, square-unit factors are the square of the linear factor; a square foot is 0.3048² = 0.09290304 m².
An acre is defined as exactly 4,046.8564224 m² and a hectare is 10,000 m², the area of a square 100 m on each side.
