Manzana (unit)
A manzana is a unit of area used in Argentina and in many Central American countries, originally defined as 10,000 square varas in Spanish customary units. In other Spanish-speaking regions, the term has the meaning of a city block. Today its size varies between countries: * In Argentina it is a hectare, 10,000 m2. * In most Central American countries it is about 7,000 m2 (1.7 acres), varying between countries. * In Belize it is 8,353 m2 (2.064 acres). * In Nicaragua it is 7,042.25 m2 (1.74018 acres). If a vara is taken as 83.59 cm, then a manzana of 10,000 square varas is equal to 6,987.29 m2. In calculations, the approximate value of 7000 m2 (or equivalently 0.7 ha) is often used to simplify conversion. (Wikipedia).
