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

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 Rod (US Survey): A Comprehensive Explanation
Definition of Square Rod (US Survey)
The square rod (US survey) is a measure of area based on the rod, which is a linear measure used in surveying of land. In our context, one square rod is equal to the area of the square formed if each side of it measures one rod.

Historical of Square Rod (US Survey)
Rod, also called perch or pole, is a UK unit of length that is equivalent to one times 16.5 feet or 5.5 yards. From the above linear standard, the square rod came as a unit for measurement of small portions of land. It has been in existence since the medieval England social system and was common in the United States, especially in the subdivision of land and in agricultural sectors.
In the US survey system, somewhat different from the international system of definitions of length, the square rod was used in the Public Land Survey System (PLSS) for subdividing and describing land.
Modern Usage
The US has largely made use of metric and modern imperial units, but the square rod is occasionally mentioned in the old legal papers, property documents, and historical data. It is still relevant to address issues pertaining to historical partitioning of land and real estate dimensions.
Notable Uses in Agriculture and Real Estate
- Agriculture: In the past, the square rod was applied in the plots, such as fields and planting areas, as well as measuring the productivity of land. Its use enabled a fine division of land into measurable portions suitable for farming.
- Real Estate: Thus, in the nineteenth and at the beginning of the twentieth centuries, the square rod was widely used in the rural regions in sales of land and property descriptions. It should be noted that even to the present day, many older records of properties in the United States have units expressed in the square rods.
