What Is This Tool?

This unit converter facilitates the transformation of area values measured in Are (a metric unit equal to 100 square meters) into the US survey-based Square mile, commonly applied in United States land surveys and property records.

How to Use This Tool?

  • Enter the area value in Are (a) that you want to convert.
  • Select Are as the input unit and Square mile (US survey) as the output unit.
  • Click the convert button to obtain the equivalent area in square miles (US survey).

Key Features

  • Converts Are units, used for small to medium land measurements, into Square miles based on US survey feet.
  • Supports understanding of legal and cadastral property sizes in US customary units.
  • Browser-based and easy-to-use interface for fast area unit conversions.

Examples

  • 100 Are equals 0.00386101 square mile (US survey).
  • 500 Are equals 0.01930505 square mile (US survey).

Common Use Cases

  • Converting small-plot land sizes from metric units to US survey units for legal documentation.
  • Integrating agricultural planning data with US Public Land Survey System records.
  • Preserving legacy GIS and cadastral data by translating metric-based measurements to US survey units.

Tips & Best Practices

  • Verify you are using the US survey foot definition when working with square mile (US survey) units.
  • Be cautious of unit differences in international versus US survey feet when comparing or reporting data.
  • Confirm legacy data source units to ensure correct conversions and avoid errors.

Limitations

  • Square mile (US survey) differs from international units; confusion can occur in cross-border reports.
  • Small conversion factor may lead to precision challenges for very large or very small area values.
  • Legacy measurement definitions might vary slightly, requiring careful unit identification before converting.

Frequently Asked Questions

What is an Are (a) unit used for?
