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
The are can be converted to various other units of area:
Square Meters:1 Are = 100 square meters. This is the fundamental metric conversion.
Square Feet:1 Are = 1,076.39 square feet. Commonly used in countries like the United States where the Imperial system is prevalent.
Square Yards:1 Are ≈ 119.6 square yards. Useful for land measurement in some English-speaking countries.
Acres:1 Are ≈ 0.0247 acres. Conversion to acres is often necessary for international comparisons or in agricultural and real estate contexts.
Hectares:1 Hectare = 100 Ares. The hectare is more commonly used for measuring large tracts of land, such as farms or forests.
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.
Square Mile (U.S. Survey): A Comprehensive Explanation
Definition of Square Mile (U.S. Survey)
The area measurement commonly referred as the square mile is applied in the United States and it refers to a square mile according to the U.S. survey. It denotes the area of a square whose sides are equal to one mile, U.S. survey miles, which is longer than the international miles. New units A square mile equals to 039393 square kilometer, 0.3861 square kilometer, 3097600 square yards or 27878400 square feet. Currently the definition of the U.S. survey mile is adopted as 5,280 U.S. survey feet, where 1 survey foot = 1200/3937m. This division can be credited to the methods of surveying used in United States in the past.
Conversions to Other Units
The square mile (U.S. survey) can be converted to other units as follows:
Today, a square mile is subdivided from the Roman-British systems, and although the meaning of a U.S. survey definition is much more precise, it is rooted in the General Land Office surveying methods in the eighteenth and nineteenth centuries. The unit was made constant for use in the westward expansion of the United States in the division of land and the layout of property boundaries. Square miles were important for using the most popular land dividing method called the Public Land Survey System, which divided it into townships, sections, and parcels in order to sell and manage it more efficiently. The areas of each township were intended to be 36 square miles and subdivided into thirty-six 1 square mile tracts.
Use in Land Measurement Today
The square mile (U.S. survey) remains a key unit in the measurement of large land areas in the United States. It is used in the following contexts:
Geographic Areas: Square miles are commonly employed in discussing the area of cities, counties, states, and some other territories.
Land Division: The sections and townships used in the PLSS are described with reference to square miles in surveying and allocation of land.
Real Estate and Agriculture: Square miles are used as a unit of measurement when it comes to large chunks of agricultural or unimproved land, mostly in rural or government land.
Notable Uses of the Acre in Agriculture and Real Estate
Since 1 square mile equals 640 acres, the acre becomes a smaller, more practical unit for individual parcels within a square mile.
Agriculture: Consumers and producers estimate planting areas and output in terms of acres, while square miles include a broader planning unit at the regional level.
Real Estate: It assists in estimating and planning other small or big-scale developments on large pieces of land, such as subdivisions of land or business use.
