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.
Conversion to Other Units
The circular mil is a small unit of area, and its conversions include:
1
circular mil = 7.854 × 10⁻⁷
square inches1
circular mil ≈ 5.067 × 10⁻⁶
square centimeters1
circular mil ≈ 7.297 × 10⁻¹⁰
square feet1
square inch = 1,273,239

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.
Comprehensive Explanation of the Section as a Unit of Measurement
Definition of Section
A section is a part of the United States PLSS that measures the extent of land as a division and sub-division. One section is a square area with an area of 1 mile at each side, or 640 acres or 2.58999
square kilometers. The use of sections is very helpful in the division as well as the description of land especially in country and agricultural property.
Historical of Section
Originally, the section developed originated from the Land Ordinance of 1785
that provided for the creation of the public land survey system (PLSS) with the purpose of providing for surveys of the land in the United States, especially in the western areas. The system distributed land into townships and sections and fractions of such sections. A township is a six-by-six-mile square that is made up of 36
sections.
Further, the constantly changing geographical boundaries meant that a standardized system of conveying and dealing in land was possible only if it was clearly defined.
Conversion to Other Units
A section can be converted into various land measurement units:
- Square Feet:
1
section = 27,878,400
square feet - Square Yards:
1
section = 3,097,600
square yards - Acres:
1
section = 640
acres - Hectares:
1
section ≈ 259
hectares Each section is further divided into smaller units, such as quarter sections (160
acres) and quarter-quarter sections (40
acres), which were commonly distributed under the Homestead Act.
Use in Land Measurement Today
Sections remain a vital part of land measurement and legal descriptions in the United States. They are widely used in:
- Surveying: Land parcels are often described in terms of sections and their subdivisions, such as the northeast quarter of Section 10.
- Agriculture: Farmers and ranchers often own or lease land measured in sections or fractions thereof.
- Real Estate: Sections are used in legal documents to define property boundaries, especially in rural and undeveloped areas.
Notable Uses in Agriculture and Real Estate
- Agriculture: Sections and their sub-divisions such as quarter section is used widely in distributing farmland. A quarter section measuring is 160 acres and was considered long back to be easily managed by a family for farming.
- Real Estate: Sections afford a definitive method of defining large areas of land in legal and business processes. They are especially crucial for purposes of zoning, taxation, and resource management.
