One acre equals 1 ⁄ 640 (0.0015625) square mile, 4,840 square yards, 43,560 square feet, [2] or about 4,047 square metres (0.4047 hectares) (see below).While all modern variants of the acre contain 4,840 square yards, there are alternative definitions of a yard, so the exact size of an acre depends upon the particular yard on which it is based.
The rod is useful as a unit of length because integer multiples of it can form one acre of square measure (area). The 'perfect acre' [2] is a rectangular area of 43,560 square feet, bounded by sides 660 feet (a furlong) long and 66 feet (a chain) wide (220 yards by 22 yards) or, equivalently, 40 rods by 4 rods. An acre is therefore 160 square ...
An acre is an area that is one furlong long and one chain (66 feet or 22 yards) wide. For this reason, the furlong was once also called an acre's length , [ 2 ] though in modern usage an area of one acre can be of any shape.
Acre: 4,047 m 2: An area of land one chain (four rods) wide by one furlong in length. As the traditional furlong could vary in length from country to country, so did the acre. In England an acre was 4,840 square yards (4,050 m 2), in Scotland 6,150 square yards (5,140 m 2) and in Ireland 7,840 square yards (6,560 m 2). It is a Saxon unit ...
The acre is also commonly used to measure land areas, where 1 acre = 4,840 square yards = 43,560 square feet. An acre is approximately 40% of a hectare. On the atomic scale, area is measured in units of barns, such that: [13] 1 barn = 10 −28 square meters. The barn is commonly used in describing the cross-sectional area of interaction in ...
Rood is an English unit of area equal to one quarter of an acre [2] or 10,890 square feet, exactly 1,011.7141056 m 2. A rectangle that is one furlong (i.e., 10 chains, or 40 rods) in length and one rod in width is one rood in area, as is any space comprising 40 perches (a perch being one square rod).
In Australia and New Zealand, most building lots in the past were a quarter of an acre, measuring one chain by two and a half chains, and other lots would be multiples or fractions of a chain. [19] The street frontages of many houses in these countries are one chain wide—roads were almost always 1 chain (20.1 m) wide in urban areas, [ 19 ...
what is width of an acre in feet? 1 yard = 3 feet, so, 220 yd by 22 yd = 660 by 66 feet. Thus, 66 feet wide. Nik42 08:04, 11 Feb 2005 (UTC) If your "acre" is a rectangle, then its width is 43,560 ft² divided by the length in feet.
