About the acre
The acre began as the area a team of oxen could plough in a day and was fixed in England as a strip one furlong long and one chain wide. Today’s international acre is exactly 43,560 sq ft, 4,840 sq yd, 10 square chains or 160 square rods, and since the 1959 yard and pound agreement it is exactly 4,046.8564224 m².
Across South Asia many local units are defined from the acre: the cent and the decimal are 1/100 acre, the guntha 1/40, the kanal 1/8 and the marla 1/160, while a killa in consolidated Punjab land is one acre. Older Punjab records call the acre a ghumaon.
The US survey acre, used in many US land surveys before the US survey foot was retired at the end of 2022, is larger by about 4 parts per million, or about 0.016 m² per acre. That difference matters only for very large tracts.
