Square foot

The square foot (plural 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 Bangladesh, Canada, Ghana, Hong Kong, India, Liberia, Malaysia, Myanmar, Nepal, Pakistan, Singapore and the United Kingdom.[citation needed] It is defined as the area of a square with sides of 1 foot.

Acre

The acre is a unit of land area used in the imperial and US customary systems. It is traditionally defined as the area of one chain by one furlong (66 by 660 feet), which is exactly equal to 10 square chains, 1/640 of a square mile, or 43,560 square feet, and approximately 4,047 m², or about 40% of a hectare. Based upon the International yard and pound agreement of 1959, an acre may be declared as exactly 4,046.856 422 4 square metres. One recognised symbol for the acre is ac, but the word 'acre' is also used as the symbol.
