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 161⁄2 feet, equal to exactly 1⁄320 of a mile, or 51⁄2 yards (a quarter of a surveyor's chain), and is exactly 5.0292 meters.
These bars often used a unit of measure called a rod, of length equal to 5.5 yards, 5.0292 metres, 16.5 feet, or 1 ⁄ 320 of a statute mile. [23] A rod is the same length as a perch or a pole. [24] In Old English, the term lug is also used.
The chain (abbreviated ch) is a unit of length equal to 66 feet (22 yards), used in both the US customary and Imperial unit systems. It is subdivided into 100 links. [1][2] There are 10 chains in a furlong, and 80 chains in one statute mile. [2] In metric terms, it is 20.1168 m long. [2] By extension, chainage (running distance) is the distance ...
Among the important units of distance and length at the time were the foot, yard, rod (or pole), furlong, and the mile. The rod was defined as 5 + 1 ⁄ 2 yards or 16 + 1 ⁄ 2 feet, and the mile was eight furlongs, so the definition of the furlong became 40 rods and that of the mile became 5,280 feet (eight furlongs/mile times 40 rods/furlong ...
Measurement of area. 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).
Rute – Rod, Roman origin, use as land measure. Very differing definitions, 10, 12, 14, 15, 18 or 20 feet, varied between approx. 3 and 5 m. Wegstunde – 'Way's hour', one hours travel (by foot), used up to the 18th century. In Germany 1 ⁄ 2 Meile or 3.71 km, in Switzerland 16000 feet or 4.8 km
A quarter chain, or 25 links, measures 16 feet 6 inches (5.03 m) and thus measures a rod (or pole). Ten chains measure a furlong and 80 chains measure a statute mile. [1] Gunter's chain reconciled two seemingly incompatible systems: the traditional English land measurements, based on the number four, and decimals based on the number 10.
The basic unit of Roman linear measurement was the pes (plural: pedes) or Roman foot. Investigation of its relation to the English foot goes back at least to 1647, when John Greaves published his Discourse on the Romane foot. Greaves visited Rome in 1639, and measured, among other things, the foot measure on the tomb of Titus Statilius Aper ...
