Area factors are squared
Because area has two dimensions, a linear conversion factor must be squared. One square foot is exactly 0.09290304 square metres.
Land units
Hectares and acres are convenient for land area. One hectare is 10,000 square metres.
Check the unit symbol
Square metres, square feet, and other area units are not interchangeable with their unsquared length counterparts.
