100 acres equals how many miles?

Answer 1

The two cannot be compared - acres is a unit of area, miles is a unit of length. For example, one acre is about 4000 square metres or if you had a square with the length each side as 65m, its area would be 1 acre.

Answer 2

Miles are a measure of distance, whereas an acre is a measure of surface area. Therefore, the two are not comparable.
