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, perch, or pole (sometimes also lug) is a surveyor's tool [1] and unit of length of various historical definitions. In British imperial and US customary units, it is defined as 16 + 1 ⁄ 2 feet, equal to exactly 1 ⁄ 320 of a mile, or 5 + 1 ⁄ 2 yards (a quarter of a surveyor's chain), and is exactly 5.0292 meters.
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. The term furlong, or shot, was also used to describe a grouping of adjacent strips within an open field. [3] Among the early Anglo-Saxons, the rod was the fundamental unit of land measurement.
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. A measure of 100 by 100 varas (Spanish) is almost 7000 square meters, and is known traditionally throughout Spain and Latin America as a manzana (i.e., a "city block").
