The square is an Imperial unit of area that is used in the construction industry in the United States and Canada, [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.
Adding and subtracting SI prefixes creates multiples and submultiples; however, as the unit is exponentiated, the quantities grow exponentially by the corresponding power of 10. For example, 1 kilometre is 10 3 (one thousand ) times the length of 1 metre, but 1 square kilometre is (10 3 ) 2 (10 6 , one million ) times the area of 1 square metre ...
10.6 μm – wavelength of light emitted by a carbon dioxide laser; 15 μm – width of silk fibre [citation needed] 17 μm – minimum width of a strand of human hair [25] 17.6 μm – one twip, a unit of length in typography; 10 to 55 μm – width of wool fibre [93] 25.4 μm – 1/1,000 inch, commonly referred to as 1 mil in the U.S. and 1 ...
Although there are 10 mm in 1 cm, there are 100 mm 2 in 1 cm 2. Calculation of the area of a square whose length and width are 1 metre would be: 1 metre × 1 metre = 1 m 2. and so, a rectangle with different sides (say length of 3 metres and width of 2 metres) would have an area in square units that can be calculated as: 3 metres × 2 metres ...
The National Institute of Standards and Technology formerly contended that customary area units are defined in terms of the square survey foot, not the square international foot, [17] but from 2023 it states that "although historically defined using the U.S. survey foot, the statute mile can be defined using either definition of the foot, as is ...
Square miles should not be confused with miles square, a square region with each side having a length of the value given. For example, a region which is 20 miles square (20 miles × 20 miles) has an area of 400 sq mi; a rectangle of measuring 10 miles × 40 miles also has an area of 400 sq mi, but is not 20 miles square.

The unit square in the real plane In mathematics , a unit square is a square whose sides have length 1 . Often, the unit square refers specifically to the square in the Cartesian plane with corners at the four points (0, 0 ), (1, 0) , (0, 1) , and (1, 1) .
