Convert from tarea to sitio

Unit Definition (tarea)
The tarea is a traditional unit of land area in the Dominican Republic and some parts of Central America. The tarea is generally equal to 900 square varas, so it is the area of a square 30 varas (about 25.05 meters) on a side. In the Dominican Republic, the tarea equals about 628 square meters or 751 square yards; this is 0.0628 hectare or 0.155 acre. The Spanish word tarea means a task or job, so this unit, like many land area units, originated as the area which could be "worked" in a given time.

Unit Definition (sitio)
The sitio is a name used traditionally in Mexico and the southwestern U.S. for the square legua, a unit of area equal to 25 million square varas or about 1800 hectares. The word means "place".
