The square is an Imperial unit of area that is used in the United States construction industry,[1] and was historically used in Australia. One square is equal to 100 square feet. Examples where the unit is used are roofing shingles, metal roofing, vinyl siding, and fibercement siding products. Some home builders use squares as a unit in floor plans to customers.

Buildings in Australia no longer use the square as a unit of measure, and has been replaced by square metres. The measurement was often used by estate agents to make the building sound larger as the measure includes the areas outside under the eaves, and so cannot be directly compared to the internal floor area.[citation needed] Residential Buildings in the state of Victoria, Australia are sometimes still advertised in squares.
