What Is This Tool?

This converter transforms area values from arpent, a traditional French land measurement, into square millimeters, the SI unit for very small surface areas. It is useful for connecting historical land data with current scientific and engineering requirements.

How to Use This Tool?

  • Enter the numerical value in arpent you wish to convert.
  • Select 'arpent' as the input unit and 'square millimeter [mm²]' as the output unit.
  • The tool calculates and displays the equivalent area in square millimeters.

Key Features

  • Converts arpent, a historical French unit of land area, into square millimeters (mm²).
  • Supports translation of colonial and cadastral land measurements into modern units.
  • Browser-based, easy to use, and ideal for historical, GIS, and engineering purposes.

Examples

  • Converting 2 arpent results in 6,837,785,847.3338 mm².
  • A value of 0.5 arpent converts to 1,709,446,461.83345 mm².

Common Use Cases

  • Interpreting colonial land grants and cadastral maps from Québec and Louisiana.
  • Integrating historical area measurements into modern surveying and GIS.
  • Analyzing land area data precisely in scientific and civil engineering projects.

Tips & Best Practices

  • Be aware that the size of arpent varied regionally; consider local context for accuracy.
  • Use this converter to translate large historical area units into precise small-scale SI measurements.
  • Verify converted values especially when dealing with very large numbers in mm².

Limitations

  • Arpent's exact size differs depending on the region, so adjust conversions accordingly.
  • Converting large units like arpent into square millimeters yields very large numbers that may be cumbersome.

Frequently Asked Questions

What is an arpent?
An arpent is a historical French unit of area used mainly for land measurement, commonly about 0.34 hectare or roughly 3,400 square meters.

Why convert arpent to square millimeters?
Converting to square millimeters allows precise integration of historical land data into modern surveying, GIS, and engineering workflows requiring standardized units.

Are all arpent sizes the same?
No, the size of an arpent varied by region, so exact conversions might need regional adjustments.

Key Terminology

Arpent
A historical French unit of area commonly about 0.34 hectare, used for land measurement in colonial and cadastral contexts.
Square Millimeter (mm²)
An SI-derived unit of area representing the surface of a square one millimeter on each side, used for measuring very small areas.
