Comprehensive Explanation of the Are as a Unit of Measurement
Definition of the Are
The are is a unit of area measurement in the metric system that specifically means the area of one hectare, being equal to 100
square meters. It is mainly applied in the determination of land area, and it is equal to 12.2921 square meters, or 0.0247
of an acre, or 1076.39 square feet. The is in the International System of Units (SI); however, it is not as popular as the hectare, which is 10,000 m² or 100
ares.
Historical Context
The area was established as a metric system during the French Revolution in 1793
in the late 18th century. Originally, the metric system was designed as one system for the whole of Europe, integrating many different and therefore inconsistent local systems.
Despite the are being used in metric countries, people have shifted from using the are, primarily because the hectare is more convenient in large-scale measurements. However, they are still in use in some cases, especially in subsistence farming, nurseries, gardening, or residential houses.
Conversion to Other Units
Use in Land Measurement Today
Although the are is no longer utilized much today, it is understood in some areas, mainly in Europe, Asia, and parts of Africa, in measuring Song parcels of land. It is especially relevant for:
- Gardens and Small Properties: The are is a convenient unit for measuring residential plots, gardens, or small agricultural fields.
- Urban Land Parcels: In urban settings, where land parcels are smaller, the are provides a manageable and precise measurement.
- Legal and Administrative Documents: In some countries, land deeds and legal documents may specify land area in ares, particularly for smaller lots.
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.
