About these units

Area units are squares of length units, so their factors are squared too: 1 ft = 0.3048 m means 1 ft² = 0.09290304 m². A hectare is a 100 m × 100 m square (10,000 m²) and an acre is 43,560 ft², exactly 4,046.8564224 m², so one hectare is about 2.471 acres. Land is usually measured in acres or hectares, and floor space in square feet or square meters.
