How much is an Acre of Land?
The acre was originally the area a yoke of oxen could plow in a day and therefore differed in size from one locality to another. It is now fixed as 10 square chains or 160 square rods, i.e., 4,840 sq yd, 43,560 sq ft, or 1/640 sq mi. It is equal to about .4047 of a hectare or 4,046.9 sq m.

An Acre of land is a measure of land equal to 43,560 square feet, 4,840 square yards or 160 square rods. A
square parcel of land measuring 208.71 feet on each side contains one acre. There are
640 acres in a "section" of land.

In the United States, since the acre is a land measure it is currently based on the U.S. survey foot and not on the international foot. One acre is about 4,046.873 square meters.

1 sq mile (2.59 sq km) equals 640 acres.
