Surveyors use Square Chain to Township as a conversion method to determine land size in both land surveying and real estate fields.The area measurement of a square chain comes to 4,356 square feet because it consists of one chain (66 feet) length on all sides. One township exists as a common measurement in the United States Public Land Survey System (PLSS) with a size of 36 square miles (23,040 acres). Surveyors and developers together with GIS professionals need to understand this conversion because 1 township represents 1600 square chains. The correct conversion between these units provides exact land area measurements while facilitating productive management of agricultural fields in addition to enhancing city development and real estate assessment processes.
Comprehensive Explanation of the Square Chain as a Unit of Measurement
Definition of Square Chain
A square chain is a unit of distance in geometrical surveying identifiable by ability to measure area through real estate. It gave an area of the square of one chain in each side. A chain is a form of traditional length measuring 66 feet of length or 22 yards. Therefore:
In metric terms, 1 square chain ≈ 404.686 square meters.
It is also commonly expressed in relation to other traditional units:
1 square chain = 484 square yards.
10 square chains = 1 acre
Historical of Square Chain
It was 66 feet long and was calibrated into 100 links and was therefore used to standard measures of distances and areas.This led the evolution of the square chain as another consolidation of this system for estimating land surface. It became popular in the era of colonization especially among the British colonies like the America, Canada and Australia because of a surveying in the allocation of the land for settlers. Gradually little by little the use of the square chain eased off due to the introduction of the metric system in many parts of the world today. Nevertheless, it is used in historical related contexts and where the customs of measuring the land are still in practice.
Conversion to Other Units
The square chain can be converted into other units of area as follows:
Square Feet:1 square chain = 4,356 sq ft
Square Yards:1 square chain = 484 sq yd
Acres:1 square chain = 0.1 acres
Hectares:1 square chain ≈ 0.04047 ha
Square Meters:1 square chain ≈ 404.686 m²
Use in Land Measurement Today
While the square chain is not as commonly used as modern metric units, it is still significant in certain regions and industries:
Land Surveying: The square chain is used in land surveys on some occasions the main reason being that in some parts of the world older methods of measurement are still counted their lawful measurement even in the rural tracts in United States of America and Australia.
Historical Land Records: Since GMS was conducted with parish records for preparing the historical documentary, it has been observed that many records and deeds mention the measurement of land areas in terms of square chains and so understanding of this unit of measurement is inevitable for interpretation.
Real Estate: Within areas where traditional techniques of land surveying are still in use, the square chains might still be used in the description of Lots particularly when in the agricultural or large rural area use.
Notable Uses in Agriculture and Real Estate
Agriculture: Recorded in the past, farmers and land owners has adopted the square chain to designate portions of their field. Its simple conversion rate with the acre is 10 square chains equals one acre which made it suitable for the sub division of farmland.
Real Estate: Historically square chains could be used in legal deeds or contracts for transfers and sales of vast pieces of land. There application is usually useful in providing link between the past and the present techniques of measurement.
A township is a unit of area measurement that prevails mainly in the United States and is part of the PLSS. It refers to a square-shaped land unit that occupies an area of 36 square miles, being 6 by 6 miles.
Conversion to Other Units
A township can be converted into other units of area as follows:
The idea of the township was developed from the provision in the Land Ordinance of 1785, which intended to order land surveys for the orderly apportioning of land and selling of the public lands in the United States of America. The PLSS established townships and sections of land as a method to arrange the expansion of the western region.
Townships and Sections: A township is divided into 36 sections, and each such section is equivalent to 1 square mile or 640 acres. Some of the division possibilities of sections were for development into smaller parcels for subsequent sale or distribution.
The grid-like township system was intended to ease surveying and selling of land, as well as issuing documents of transfer of the ownership of land in newly procured territories.
Modern Usage
Townships are still used in land surveying and legal descriptions of property in the United States. Their applications include:
Land Ownership and Management: Townships form a useful basis for defining a land parcel, especially when the land is located in rural and relatively ill-developed regions.
Property Deeds: In legal descriptions of land, some of the basic landmarks used include townships, ranges, whether east or west of a principal meridian, and sections.
Land Planning: A township may be defined as an important aspect of regional planning as well as land resource planning and development.
Notable Uses of the Acre in Agriculture and Real Estate
The acre, as a smaller unit of measurement, is integral to understanding the divisions within a township:
Agriculture: The formation of townships means that farmers were able to buy land in portions, usually starting at one section (640 acres) or smaller aliquots (e.g., forty-acre sections).
Real Estate: Today, property transfers in the countryside often involve reference to township legal descriptions. For example, a deed may define a plot within a specific township, range, and section.
