Definition of the Circular Mil
A circular mil represents the area of a circle with a diameter of one mil, where:
1
mil = 1/1000
inch (0.001
inch).- However, in the circular mil system, the area of a circle with a 1-mil diameter is defined as exactly
1
circular mil, bypassing the need for π in the calculation.
Circular Mil Historical
The circular mil was adopted to supplement the well-established standard as a unit of measure for the cross-sectional area of circuit conductors, especially wires and cables. It came into existence at the time of the formation of modern electrical systems in the 19th and 20th centuries when engineers needed a manner to measure cross-sectional areas of wires and their electrical performance.
Due to its simple concept, it was accepted on a large scale in the electrical industry most notably in North America where it forms part of the wire gauge numbering system.

Use in Measurement Today
The circular mil remains a critical unit in the electrical and engineering industries, particularly for:
- Electrical Conductors: Applied for definition of the cross-sectional area of wires and cables. Crucial in calculating the current capability of a given wire, its opposition to the stream of current and voltage drop.
- Wire Sizing Standards: Often encountered in the American Wire Gauge (AWG) system used for measuring wire areas in circular mils.
- High-Voltage Systems: Used mainly in construction of high voltage transmission cables.
- Safety and Regulation: Ensures that electrical installations will operate at the design load by avoiding such features like overheating or voltage drop.
Comparison to Land Measurement Units
The circular mil is not even remotely connected to any sort of geographical or plotted area as is the case with the area units like acre or square feet, or to agriculture or real estate. Its use is limited to areas comprising small regions associated with electrical and mechanical systems.
- Land Measurement Units: 1. Designed for large areas like fields acre may be used or when measuring building spaces may use square feet. 2.On the other hand, the circular mil measures small parts of the area that could support electrical conductors.
Notable Uses
- Electrical Engineering: If a wire has a cross-sectional area of
1000
circular mils it is called kcmil or thousand circular mils used in large cables. - Telecommunications: Formerly applied to compute the resistance and capacitance respective of the wires involved in communication systems.
- Industrial Applications: Is involved in designing of motors windings, transformers and any electric devices.
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:

square yards27,878,400
square feet2.589988
square kilometers2,589,988.11

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.
