What Is This Tool?

This converter allows you to transform area values from square chains (ch^2), an imperial unit often used in cadastral surveying and historical land measurement, into acres (US survey) [ac], the standard land area unit used in U.S. surveying and legal documents.

How to Use This Tool?

  • Enter the area value in square chains (ch^2) you want to convert
  • Select 'square chain [ch^2]' as the input unit and 'acre (US survey) [ac]' as the output unit
  • Click the convert button to see the converted area in acres (US survey)
  • Use the result for land measurement, surveying, or legal documentation purposes

Key Features

  • Converts square chains directly to U.S. survey acres with precise conversion rates
  • Ideal for interpreting historical land records and modern cadastral maps
  • Supports land measurement tasks involving imperial and U.S. customary units
  • Browser-based and easy to use without installation
  • Provides clear results consistent with U.S. legal and surveying standards

Examples

  • 5 square chains equals approximately 0.499998 acres (US survey)
  • 10 square chains equals approximately 0.999996 acres (US survey)

Common Use Cases

  • Calculating parcel areas during land surveying in regions using imperial units
  • Translating land area measurements on historical deeds and maps to acres
  • Recording land sizes in U.S. property deeds and legal boundary descriptions
  • Interpreting agricultural land statistics based on U.S. survey feet
  • Converting historical chain-based measurements for modern cadastral records

Tips & Best Practices

  • Double check unit selections before performing the conversion
  • Use this tool when dealing with U.S. legal land descriptions referencing survey acres
  • Refer to historical data carefully to ensure correct unit context (square chains vs acres)
  • Remember that slight differences exist between U.S. survey feet and international measurements
  • For large area conversions, verify results with relevant cadastral records

Limitations

  • The acre (US survey) unit is based on the U.S. survey foot which slightly differs from the international foot
  • Minimal discrepancies may occur when comparing measurements with non-U.S. systems
  • The tool does not account for conversions involving units other than square chains and US survey acres
  • This converter assumes use within contexts familiar with imperial and U.S. customary measurement systems

Frequently Asked Questions

What is a square chain?
A square chain is an imperial unit of area defined as the area of a square with each side one chain (66 feet), equal to exactly 4,356 square feet.

How is the acre (US survey) different from an international acre?
The U.S. survey acre uses the U.S. survey foot, making it very slightly larger than the international acre, and it is primarily used in U.S. land surveying.

Why convert from square chains to acres (US survey)?
Converting helps interpret and communicate land areas in modern legal and cadastral contexts where acres are the standard, while still referencing historical units like chains.

Key Terminology

Square Chain [ch^2]
An imperial area unit equal to the area of a square with sides of one chain (66 feet), equivalent to 4,356 square feet or one-tenth of an acre.
Acre (US survey) [ac]
A U.S. land area unit based on the U.S. survey foot, equal to 43,560 square survey feet, commonly used in U.S. property deeds and cadastral surveying.
U.S. Survey Foot
A unit of length used in U.S. surveying that differs slightly from the international foot, used in defining the US survey acre.
