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).
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 ...

The only thing that changed was the number of feet and yards in a rod or a furlong, and the number of square feet and square yards in an acre. The definition of the rod went from 15 old feet to 16 + 1 ⁄ 2 new feet, or from 5 old yards to 5 + 1 ⁄ 2 new yards. The furlong went from 600 old feet to 660 new feet, or from 200 old yards to 220 ...
The marla is a traditional unit of area that is used in India, Pakistan and Bangladesh. The marla was standardized under British raj to be equal to the square rod, or 272.25 square feet, 30.25 square yards, or 25.2929 square metres. As such, it was exactly one 160th of an acre.
The Irish acre or plantation acre measured one Irish chain by one Irish furlong, or 4 Irish perches by 40, or 7840 square yards: approximately 0.66 hectares or 1.62 statute acres. [54] The Lancashire acre around the Solway Firth and the Churchland acre in Yorkshire were the same size, which Frederic Seebohm in 1914 connected to the erw of Gwent ...
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 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.
