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

The square foot (plural square feet; abbreviated sq ft, sf, ft2) is an imperial unit and U.S. customary unit (non-SI, non-metric) of area, used mainly in the United States and partially in Bangladesh, Canada, Ghana, Hong Kong, India, Malaysia, Nepal, Pakistan, Singapore and the United Kingdom.[citation needed] It is defined as the area of a square with sides of 1 foot.

Although the pluralisation is regular in the noun form, when used as an adjective, the singular is preferred. So, a flat measuring 700 square feet could be described as a 700 square-foot flat, this corresponds to common linguistic usage of foot.

A symbol for square foot, square feet, and "per square foot" commonly used in architecture, real estate and interior floor plans is a simple square with a vertical line bisecting it—⏍. It is also occasionally written as a square with a slash through it.[citation needed]
