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.
A killa or acre is measured rectangularly, reckoned as an area 36 karams (198 ft) x 40 karams (220 ft) (43,560 square ft). 1 /5th of a killa or acre is known as bigha 1 /5th of a killa or acre is known as bigha

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 m 2 , or about 40% of a hectare .
The vara can be seen in many deeds as late as the mid to late 1900s. 1 acre (0.405 ha) is equivalent to 5,645.376 Texan square varas. A league is equivalent to 5,000 varas squared or 4,428.4 acres (1,792.11 ha). Standardisation of measurement in Texas came with the introduction of varas, cordeles, and leagues.
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 ...
A number of different units of measurement were used in Sri Lanka to measure quantities like length, mass and capacity from very ancient times. [1] Under the British Empire, imperial units became the official units of measurement [2] and remained so until Sri Lanka adopted the metric system in the 1970s.
In Puerto Rico, a cuerda is a traditional unit of land area nearly equivalent to 3,930 square meters, [1] [2] or 4,700 square yards, 0.971 acre, or 0.393 hectare (ha). The precise conversion is 1 cuerda = 3,930.395625 m 2. [2] The term "Spanish acre" instead has been used sometimes by mainlanders. [1]
