Comparison of 1 square foot with some Imperial and metric units of area

The square foot (pl. square feet; abbreviated sq ft, sf, or ft2; also denoted by '2) 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, the United Kingdom, Bangladesh, India, Nepal, Pakistan, Ghana, Liberia, Malaysia, Myanmar, Singapore and Hong Kong.[citation needed] It is defined as the area of a square with sides of 1 foot.

Although the pluralization is regular in the noun form, when used as an adjective, the singular is preferred. So, an apartment measuring 700 square feet could be described as a 700 square-foot apartment.[citation needed] This corresponds to common linguistic usage of foot.

The square foot unit is commonly used in real estate.[1] Dimensions are generally taken with a laser device, the latest in a long line of tools used to gauge the size of apartments[2] or other spaces. Real estate agents often measure straight corner-to-corner, then deduct non-heated spaces, and add heated spaces whose footprints exceed the end-to-end measurement.[3]
