Tips & Best Practices
-
Ensure you understand the historical context of the arpent as its size varied regionally
-
Use the tool for general conversions and verify precision in legal or technical cases
-
Be aware of differences between the US survey foot and the international foot when comparing units
-
Cross-check conversions when applying results to modern surveying standards
Limitations
-
Exact arpent size can vary depending on regional historical definitions
-
The square foot (US survey) differs slightly from the international square foot, affecting precision
-
Modern surveying may require additional standardization beyond this historical conversion
