What Is This Tool?

This tool allows you to convert area values from the U.S. survey acre to the square pole unit. It is designed for users working with land measurement systems found in U.S. and UK surveying and cadastral records.

How to Use This Tool?

  • Enter the area value in acre (US survey) that you want to convert
  • Select 'acre (US survey)' as the input unit and 'square pole' as the output unit
  • Click the convert button to get the equivalent area in square pole
  • Review the converted value to interpret or compare land measurements accurately
  • Use multiple conversions to analyze or document land parcel sizes

Key Features

  • Converts acre (US survey) precisely to square pole based on official definitions
  • Ideal for land surveying, property deed analysis, and historical land records
  • Browser-based, easy to use without any downloads
  • Supports legal and cadastral record interpretation requiring both units
  • Includes clear examples illustrating typical conversions

Examples

  • 2 acre (US survey) converts to 320.00128 square pole
  • 0.5 acre (US survey) converts to 80.00032 square pole
  • Use the formula: 1 acre (US survey) = 160.0006400019 square pole

Common Use Cases

  • Describing U.S. property deed parcel sizes and boundaries
  • Converting and interpreting historical land survey records in the U.S. and UK
  • Migrating older cadastral records to modern measurement systems
  • Surveying and legal documentation where imperial units remain in use
  • Assessing agricultural land areas recorded using U.S. survey-foot data

Tips & Best Practices

  • Always confirm the units used in your source data to avoid inaccuracies
  • Consider the slight size difference between the US survey acre and international acre
  • Use this converter primarily for historical or legal contexts where both units appear
  • Cross-verify results when high precision is required due to subtle rounding variations
  • Keep in mind that square pole is largely a historical unit and less common in modern use

Limitations

  • The US survey acre is slightly larger than the international acre, affecting exactness
  • Square pole is mostly a historical or regional measurement unit, not widely used today
  • Minor rounding differences can occur because of the exact definitions involved
  • Modern surveying often prefers metric or standard imperial units over square pole

Frequently Asked Questions

Why is the US survey acre different from the international acre?
The US survey acre is defined using the US survey foot, which differs slightly from the international foot, making the US survey acre a bit larger than the international acre.

When should I use square pole for area measurements?
Square pole is typically used in historical or traditional land surveys, legal property descriptions, and when working with older cadastral records that include imperial units.

Can I use this converter for modern land surveying?
While the converter is helpful for historical and legal contexts, modern surveying often uses metric or standardized imperial units instead of square pole.

Key Terminology

Acre (US survey)
An area unit defined as 43,560 square U.S. survey feet, used mainly in U.S. land surveying and legal boundaries.
Square pole
An imperial area unit equal to a square with sides of one pole (rod), equivalent to 272.25 square feet or 1/160 of an acre.
U.S. survey foot
A foot measurement exactly equal to 1200/3937 meters, used in defining the US survey acre.
