Quoting from the book [1]:
<quote>
Units of Linear Measure
1 chain = 100 links
= 66 feet
1 mile = 80 chains
= 5280 feet
Units of Area
1 acre = 10 square chains
= 43,560 square feet
1 square mile = 640 acres
The chain unit, devised in the seventeenth century, by Edmund Gunter,
an English astronomer, is so designed that 10 square chains are
equivalent to one acre. In the english colonial area of the United
States the boundries of land were usually measured in the chain unit,
lengths of lines were expressed in poles. One pole is equal to 25 links,
and four poles equals one chain. The field notes of some early
rectangular surveys in the southern States show the distance in
"perches," equivalent to poles. The term now commonly used for the same
distance is the rod.

It goes on to talk about the french using "arpents" and the spanish and
mexican using "varas".
Does this help ?
