How many square feet in a square acre?

Answer 1

There are 43,560 square feet in one acre. An acre is a unit of area. 640 acres equal a square mile. Hence, it is 1/640 of a square mile. Since a square mile contains 27,878,400 square feet, an acre is 27,878,400 divided by 640, which is 43,560 square feet.

Remember: an acre can be converted to SQUARE feet, not plain (linear) feet. Square feet and feet are not the same units. A foot is unit of distance. A square foot is a unit of area.
