Convert foot (spanish) to inch

The inch has been exactly 2.54 cm since 1959; 12 inches make a foot, 3 feet a yard and 1,760 yards a mile of 1.609 km. The US and UK still use them for heights (5 ft 10 in is 178 cm), road distances and speed limits, and the inch survives everywhere in screen sizes, wheel rims and pipe threads. Five miles are almost exactly eight kilometres, a handy road-sign rule.

The vara of Burgos, 0.8359 m, was Spain's standard yard from 1801 until the metre replaced it; it divided into 3 pies (feet), 36 pulgadas (inches), 432 líneas and 5,184 puntos, and a paso (pace) was 5/3 of a vara. The vara travelled to the colonies and was fixed differently in each: 0.838 m in Mexico, 0.866 m in Argentina, and 33⅓ inches (0.847 m) in Texas and California, where old land grants are still described in varas.
