Convert from morgen [South Africa] to labor

Unit Definition (morgen [South Africa])
The morgen is a traditional unit of land area in Northern Europe. "Morgen" means "morning," and most likely the unit arose as the area a yoke of oxen could plow in one morning. The Dutch morgen, also used in Dutch colonies including old New York, equals about 2.10 acres or 0.850 hectare. In South Africa, this unit was defined to equal 10 246 square yards, which is 2.1169 acres or 0.8567 hectare. In Scandinavia and northern Germany, the morgen is a smaller unit equal to about 0.63 acre or 0.25 hectare (2500 square meters). The Prussian morgen, standardized at 2553.22 square meters, was in common use during the nineteenth century. In Austria and southern Germany, the morgen was often the same as a joch, typically defined to be 0.5755 hectare or about 1.422 acres.

Unit Definition (labor)
The labor is a traditional unit of area in Latin American countries. The labor is equal to the area of a square 1000 varas on a side, or 0.04 legua. Using the Texas standard for the vara (33 1/3 inches), this is equivalent to 177.136 acres or 71.685 hectares. The word labor means work in Spanish, as it does in English. As a unit it represents the area that could be cultivated by a single farmer, somewhat like the old English hide.
