Acres already come in squares (technically, a square acre is a volume not an area). One acre equals 0.0015625 square miles [W]. To convert a population density per square mile into per acre, multiply it by 0.0015625. (To convert a population density per acre into per square mile, divide it by 0.0015625.)
