The square foot (plural square feet; abbreviated ft 2 or sq ft) is an imperial unit and U.S. customary unit (non-SI, non-metric) of area, used mainly in the United States and partially in Canada, United Kingdom, Hong Kong, Bangladesh, India and Pakistan. It is defined as the area of a square with sides of 1 foot.
Square foot can also be defined as area of square with sides of 1 foot in length. Linear feet is that length which is measured in feet. We know that area is product of length and width. So for change of square feet into linear feet, length or width must be in square feet.
