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

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 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.

square foot (US survey) is equal to:
144
square inches.0.1111
square yards.0.0929034116
square meters (approximately).
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
.
Conversion to Other Units
The square foot (US survey) can be converted to various units of area:
- Square Inches:
1
ft² = 144
in² - Square Yards:
1
ft² = 0.1111
yd² - Square Meters:
1
ft² = 0.0929034116
m² - Acres:
1
acre = 43,560
ft² - Square Miles:
1
mile² = 27,878,400
ft²
Use in Land Measurement Today
The square foot (US survey) is primarily used in contexts where precision is critical, particularly in:
- Land Surveys: A reference area measurement commonly used by surveyors involves the small land areas, especially where the previous survey data was based on the square foot (US survey).
- Construction: People in the construction sector use square feet to measure floors and building plans, among other things.
- Real Estate: acres, hectares, and square feet are normally used to describe the area of residential and commercial buildings.
- Mapping and GIS: Further, land analysis and planning in Geographic Information Systems (GIS) also include square foot measurements.
Notable Uses in Agriculture and Real Estate
- Agriculture: Square feet are used to quantify the sq ft area used for specializing crops, mini plantations, testing beds, mini-green houses, or efficient watering spans.
Where larger surfaces are being considered, measurements are often given in acres or hectares, but square feet give fine details in localized operations. - Real Estate: Square feet are the common unit of measurement of the size of homes and offices, as well as other buildings and properties in the US.
Actual or usable area of space is portrayed to either increase property value and hence appeal by means of listing size or by showing available space within property.
Comparison with the Acre
While the square foot (US survey) and the acre are both units of area measurement, their scales are vastly different:
1
acre = 43,560
square feet (US survey).- Square feet are more granular and used for smaller-scale measurements, whereas acres are suited for large-scale land measurement, such as farms or estates.
