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 Rood as a Unit of Measurement
Definition of Rood
The rood also refers to one of the old English units of measurement of land area and length. A rood is one of the measurements of area; it is equal to a quarter of an acre, 10,890
sq ft, 1,210
sq yd or approximately 1,011.71
sq m. As a unit of length it is equal to a rod, pole, or perch and is equal to 16 ½ feet or 5.03
meters.
The rood was utilized for the division of land and particularly for the division of land in agricultural and with reference to property that is real estate.
Historical of Rood
The rood has its roots in England of the middle ages when surveys of land were essential both for farming and in determining taxation. From Old English rōd 'pole', 'cross'. It was commonly used along with older traditional units such as acre, furlong, rod and a string of other units that could be easily grasp by farmers and surveyors.
In this system:
1
acre = 4
roods1
rood = 40
rods in length × 1
rod in widthThe rood's use declined with the adoption of the metric system and standardized land measurements, but it remains an important historical unit in understanding older land records and property descriptions.
Conversion to Other Units
As a unit of area, the rood can be converted into various measurements:
- Square Feet:
1
rood = 10,890
square feet - Square Yards:
1
rood = 1,210
square yards - Acres:
1
rood = 0.25
acres - Hectares:
1
rood ≈ 0.101171
hectares As a unit of length:
- Feet:
1
rod (or rood) = 16.5
feet - Meters:
1
rod (or rood) = 5.03
meters
Notable Uses in Agriculture and Real Estate
- Agriculture: Farmers historically used the rood to calculate land required for planting crops, grazing livestock, or other agricultural activities. It provided a practical way to describe smaller portions of land.
- Real Estate: The rood was used to describe property sizes in legal documents, particularly when parcels of land were smaller than an acre.
