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

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.
Definition of Electron Cross Section
Mathematically, the cross section is expressed in units of area, typically in square meters (m²) or barns, where:
1
barn = 10^-28
m²Cross sections can vary depending on the energy of the incoming electron and the nature of the target particle.
Electron Cross Section Historical
Conversion to Other Units
While the electron cross section is not typically converted into macroscopic units like square feet or square yards, its standard conversions include:
1
barn = 10^-28
m²1
barn = 10^-24
cm²For reference, a square yard or square foot is astronomically larger than the typical electron cross section:
1
square yard = 0.836127
m²1
square foot = 0.092903
m²Thus, the electron cross section is a microscopic measurement suited only for quantum-scale phenomena.
Use in Measurement Today
The electron cross section remains a vital concept in physics and is used in the following contexts:
- Atomic and Molecular Physics: In order to quantify the probability of scattering, excitation, or ionisation of electrons in atomic and molecular collisions. Says Lawton: A cross section data is highly important for studying the reaction of chemicals and plasma.
- Nuclear Physics: Employed to investigate electron-nucleus interactions in helping realize forces as well as particle behavior.
- Radiation and Material Science: Contributes to understanding how electrons behave around other objects, essential for radiation detectors and exciting properties of materials.
- Astrophysics: Cross sections describe the physical processes of the interaction of cosmic particles and matters in space.
Comparison to Land Measurement Units
Electron cross section is very different from the units used in the measurement of land such as acres, square yards, or even square feet. On the one hand, there are macroscopic units of land measurement applied in practical life as in agriculture or property surveys, while the electron cross section is a truly quantum measure applied solely for scientific purposes only.
- Used to measure land area; equal to
43,560
square feet. - Used to measure interaction probabilities; typically in the range of
10^-28
m² or smaller.
