A square foot (abbreviated as ft2) is a unit of area measurement equivalent to a square measuring 1 foot on every side. One square foot equals to approximately 0.09 square meters. A square foot is a unit of area used mostly in the imperial and U.S. customary measurement systems.
1 square foot = approximately 0.000022959 acres. 1 acre = 43,560 square feet. To calculate the area of a room in square feet, measure the length and width of the room in feet, then multiply these figures together to give an area in ftÂ².For example, a room measuring 12 ft x 15 ft would be described as having an area of 180 ftÂ² (12 x 15 = 180). 1 square yard (Sq Yd) = 9 ftÂ². 2  One yard is three feet, so a square yard can be imagined as a square with sides of three feet, or a square block comprising nine individual squares with sides one foot in length.
