What Is This Tool?
This converter transforms measurements from the arpent, a traditional French area unit used in colonial land records, into the square hectometer, an SI-derived area unit commonly used for agricultural and surveying purposes.
How to Use This Tool?
-
Enter the area value in arpent into the input field
-
Select the desired output unit: square hectometer [hm²]
-
Click the convert button to see the equivalent area
-
Use the results for mapping, analysis, or record updates

Examples
-
2 arpent converts to approximately 0.6837785848 square hectometer [hm²]
-
5 arpent converts to approximately 1.709446462 square hectometer [hm²]
Common Use Cases
-
Analyzing historical land grants in Québec and Louisiana
-
Interpreting old cadastral maps and property records
-
Measuring agricultural fields using standardized units

Tips & Best Practices
-
Verify the regional definition of an arpent for precise conversions
-
Use this tool to standardize old measurements into SI units
-
Apply results to modern surveying or GIS projects
-
Cross-check converted values when working with historical documents
Limitations
-
The arpent size has historically varied by location, making the conversion factor approximate
-
Conversion using 0.3418892924 hm² per arpent may not exactly reflect all historical records
-
Confirm the specific regional arpent definition when accuracy is critical
Frequently Asked Questions
-
What is an arpent used for?
-
An arpent is a historical French unit of area typically used to describe land parcels in colonial Québec and Louisiana.
-
Why convert arpent to square hectometer?
-
Converting arpent to square hectometer translates traditional land measurements into standardized SI units for accurate modern mapping and analysis.
-
Is the conversion from arpent to square hectometer exact?
-
No. The size of an arpent varied by region, so the conversion value is an approximate average.
Key Terminology
-
Arpent
-
A historical French unit of area used for land measurement, varying regionally but roughly equal to 0.34 hectare.
-
Square Hectometer [hm²]
-
An SI-derived unit of area equal to one hectare or 10,000 square meters, representing a square of 100 meters per side.
-
Cadastral Surveying
-
The process of mapping and recording land boundaries and property ownership, important for land management and legal purposes.
