Unit Definition (oxgang)
The oxgang is an old English unit of land area equal to 1/8 hide or roughly 15 acres (6 hectares). The hide was considered the area a farmer could plow with a team of 8 oxen, so an oxgang was the area he could plow with a single ox. The unit was also called the bovate, from the Latin word bos for an ox or cow.

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".
