    Historical of Square Mile

    Hearths of the square mile are in the ancient systems of the Roman and British ones, though the probable existence of the idea existed before the Romans and was used in the United States due to the Public Land Survey System (-) in the late 18th century. The PLSS aimed to organize land into townships and sections with a view to selling the land. They were subdivided into thirty-six townships, each of which was thirty-six square miles, and were further subdivided into thirty-six sections of one square mile, or six hundred and forty acres of land.
    Public surveying as practiced by this system was used in the westward expansion of the United States and was instrumental in the formation of the country.

    Comprehensive Explanation of the Square Foot (US Survey) as a Unit of Measurement

    Definition of Square Foot (US Survey)

    The square foot (US survey) is an area unit tied to the US survey foot, which at one point was defined as being equal to 0.1200 000 000 319 131 meters. A square foot is the area of a square that has its sides measuring one US survey foot.

    Historical of Square Foot (US Survey)

    The US Survey Foot is a measure of exactly 1/6336000 of a geographic quarter of the earth, used as a standard when surveying land in early America. This is a little dissimilar from the international foot, which is equal to 0.3048 meters. The difference is really small, but it makes a lot of difference when dealing with voluminous surveys, as in the case of the survey foot in the United States and the international survey foot.
    The chief use of the US survey system was for establishing the area's geographic maps as well as boundaries between tracts of land in the United States. The new standard for measurement was anchored to the International Foot in 1959 for many uses. However, the US survey foot was still used for all surveying in the United States and geodetic surveys until the US' National Geodetic Survey (NGS) started a transition to the international foot in the year 2022.
