In Texas, a vara was defined as 33 + 1 ⁄ 3 inches (846.67 mm), or 1 yard = 1.08 vara. [citation needed] The vara and the corresponding unit of area, the square vara, were introduced in the 19th century to measure Spanish land grants. Stephen F. Austin's early surveying contracts required that he use the vara as a standard unit.
The vara cuadrada or square vara is commonly used in land transactions in Guatemala and 10,000 square varas equal one manzana. [2] One square vara equals 0.6987 square meters (7.521 sq ft), while one manzana equals 6,987 square metres (1.727 acres). [2] The term cuerda can refer to areas of different sizes.
A number of units were used to measure length. One vara was equal to 0.836 m. [1] [2] Some other units are given below: [1] [2] 1 cuarta = 1 ⁄ 4 vara 1 tercia = 1 ⁄ 3 vara 1 mecate = 24 varas. 1 legua = 5,000 varas [3]
If a vara is taken as 83.59 cm, then a manzana of 10,000 square vara s is equal to 6,987.29 m 2. In calculations, the approximate value of 7000 m 2 (or equivalently 0.7 ha) is often used to simplify conversion.
Legua nautica (nautical league): Between 1400 and 1600 the Spanish nautical league was equal to four Roman miles of 4,842 feet, making it 19,368 feet (5,903 metres or 3.1876 modern nautical miles). However, the accepted number of Spanish nautical leagues to a degree varied between 14 1/6 to 16 2/3, so in actual practice the length of a Spanish ...
At around 600 miles wide and up to 6,000 meters (nearly four miles) deep, the Drake is objectively a vast body of water. To us, that is. To the planet as a whole, less so.
This is a list of the world's longest bridges that are more than 3 kilometers (1.9 mi) in length sorted by their full length above land and water. The main span is the longest span without any ground support.
The Chesapeake Bay Bridge, connecting the eastern and western shores of Maryland was completed in 1952. Length of the suspension span is 2,922 feet and the roadway is about 200 feet above water at ...
