Convert from tunnland to tarea

Unit Definition (tunnland)
The tunnland is a traditional unit of land area in Sweden. The tunnland is equal to 56 000 square Stockholm feet (kvadratfot); this is equivalent to 4936.4 square meters, 0.493 64 hectare, or about 1.220 English acre. The tunnland was divided into 32 kappland. Like the Danish tønde land (see above), this unit originated as the area that could be planted with one tunn (barrel) of seed.

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.
