Definition of the Circular Inch
A circular inch is the area of a circle with a diameter of 1 inch. The formula for calculating the area of a circle is:
Circular Inch Historical
The circular inch was introduced as a practical unit for measuring areas in contexts where circular cross-sections were common, such as:
- Pipe diameters
- Wire gauges
- Hydraulic and pneumatic systems
It instantly gained employment in engineering and manufacturing industries, especially in those areas of applications that entailed round features or hole measurement.
The circular inch, however, has no origin in the times of agriculture or the surveying of lands or parcels of land like the acre unit of measurement. It is relevant most to industrial and scientific purposes.
The circular inch is a relatively small unit, so its conversions to larger units of area are rarely used in practice. However, it can be expressed as:

Use in Measurement Today
The circular inch remains relevant in engineering and manufacturing, particularly in the following areas:
- Hydraulics and Pneumatics: Employed in the determination of the area within cross section of pipes, cylinder and opens at a given moments. For use in calculation of fluid flow rates and pressure throughout various elements of a system.
- Wire and Cable Manufacturing: Usually used in the measurement of wire cross sections since circles are frequently the shapes of sections of wire.
- Mechanical Engineering: It used for designing and analyzing circular shaped members such as shafts, bearings, gears etc.
- Optics and Lenses: Proves quite valuable for designing circular openings and lens.
Notable Uses
- Industrial Design: The circular inch is useful for assessing the capacity and performances of circulation based systems that incorporate circular sections.
- Aerospace and Automotive: Applied in the construction of the engines, turbines and other round engine components.
- Electrical Engineering: Part of the process of defining the cross sectional area of wires thus affecting the current carrying capability.
Square Mile: A Comprehensive Explanation
Definition of Square Mile
A square mile is a unit of area where one mile is an area of a square with one side equaling one mile in measurement. It is used all over America and other countries in measuring large tracts of land. A square mile is equal to:

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.
Use in Land Measurement Today
The square mile remains a standard unit for measuring large areas of land. Its primary uses include:
- Land Division: In the PLSS, therefore, square miles are used as units to subdivide land into easily measurable parts and aliquots.
- Agriculture: It is used to measure large-scale farms, ranches, farming areas, or regions for large-scale farming activities. Because acres are even smaller than hectares, acres are preferred for describing the actual plots or fields of farmland within a square mile.
- Real Estate: Square miles assist in estimating the area of extensive tracts of land or development ventures mainly in the country or city outskirts.
Notable Uses of the Acre in Agriculture and Real Estate
Since 1
square mile equals 640
acres, the acre serves as a more detailed unit for specific land uses within the square mile:
- Agriculture: Acres are used by farmers in order to measure the planting areas, the yield of crops, and the amount of water to be used in farming, while square miles give the broad perspective of the regional planning.
- Real Estate: This is because square miles are helpful in outlining layouts in large-scale developments like new neighborhoods or industrial tracts.
