Convert from homestead to manzana [Argentina]

Unit Definition (homestead)
The homestead is a historic unit of area in the United States, equal to 160 acres (64.75 hectares). Under the Homestead Act passed by Congress in 1862, settlers in the western states were allowed to take title to a homestead of 160 acres of land by registering a claim, settling on the land, and cultivating it. A homestead equals 1/4 square mile, or 1/4 section in U.S. government terminology.

Unit Definition (manzana [Argentina])
The manzana is a traditional unit of land area in Central America. The manzana is the area of a square 100 varas on a side; it thus varies according to the length of the vara. The Costa Rican manzana equals 0.698 896 hectares or about 1.727 acres. Very similar units are used in Guatemala, Honduras, and Nicaragua. The word manzana means an apple, but the unit is probably related to manzanar, orchard.
