Info about "Acre"
An acre (ac) is equal to one 160th part of a quarter section or one 640th part of a square mile. Thus, the acre has the area of a square with a side length of about 63.62 meters.
1 ac ≈ 63,62 m × 63,62 m
The unit acre (Old English æcer acre, field) originally referred to a strip of land that could be plowed in one day with a team of oxen.
The unit of area known as the acre is now a common unit for subdividing land areas, especially in America. These are initially divided into square miles (sections) and into quarters of these sections, namely quarters. A quarter section, in turn, consists of 160 acres. In the Anglo-American world, the size of properties in land and property surveys is indicated solely by the two area units acre and square foot.
1/640 square mile = 1/160 quarter = 1 acre = 4.840 square yards = 43.560 square feet = 6.272.640 square inches = 4.046,85642 m²
Info about "Square Foot"
A square foot (ft²; plural square feet) is equal to the area of a square with a side length of one foot (30.48 cm).
1 ft² = 1 ft × 1 ft
1 ft² = 30,48 cm × 30,48 cm
A foot is 12 inches long in the Anglo-American system and thus a square foot has 144 square inches. In the Anglo-American world, the size of land is indicated in land and property surveys using only the two area units, acre and square foot.
