How area conversion works
Area units are squared length units, so their factors are the square of the length factor. A foot is 0.3048 m, so a square foot is 0.3048 × 0.3048 = 0.09290304 m². A hectare is a 100 m × 100 m square (10,000 m²) and an acre is 43,560 ft² (4,046.86 m²).
Worked example: a 1,200 ft² apartment is 1,200 × 0.09290304 = 111.484 m². A 5-acre plot is 2.02343 hectares.
