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 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.
