Convert from bovate to tunnland

Unit Definition (bovate)
The Bovate is an old English unit of land area equal to 1/8 hide. This was roughly 15 acres or 6 hectares. The word comes from the Latin bovis, an ox, indicating that the bovate was an area that could be farmed with the help of one ox.

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.
