1 acre in square feet

One acre is exacly 1/640 of a square mile. "Forty acres", a unit in which some homesteaded plots were divided, is exactly 1/16 of a square mile, which could be a square 1/4 mile on a side, for example.

If you want a conversion of acres to square feet, hectares or square meters, may I suggest http://www.easysurf.cc/cnver5.htm
