What Is This Tool?
This tool enables you to convert measurements from rod, a traditional English unit of length, to arpent, a historical French unit of length used mainly in land measurement. It is designed to assist users handling legacy land records and surveys.
How to Use This Tool?
-
Enter the length value in rods [rd] to be converted
-
Choose the target unit as arpent
-
Click the convert button to see the corresponding length in arpent
-
Use the results for historical, surveying, or archival reference
Key Features
-
Fast and simple rod to arpent length conversion
-
Accurate application of the specific conversion rate 1 Rod = 0.0859375 Arpent
-
Supports historical and cadastral land measurement contexts
-
Ideal for legal, surveying, and heritage restoration applications
Examples
-
10 Rods = 10 × 0.0859375 = 0.859375 Arpent
-
20 Rods = 20 × 0.0859375 = 1.71875 Arpent
Common Use Cases
-
Interpreting distances and boundaries in historical land deeds
-
Describing field and fence dimensions in older agricultural surveys
-
Restoring heritage sites using legacy measurement records
-
Translating English surveying units into French colonial land measurements
-
Examining cadastral archives in Quebec and Louisiana
Tips & Best Practices
-
Verify the regional definition of arpent to improve conversion accuracy
-
Use the tool primarily for historical, surveying, or legal research purposes
-
Cross-reference converted values with archival maps or records
-
Consider context when applying conversions where arpent values varied
Limitations
-
The arpent’s exact value changed across regions and historical periods
-
Fixed rod length but variable arpent definitions may affect accuracy
-
Primarily suited for archival or legal use, not modern measurement needs
Frequently Asked Questions
-
Why is the rod unit called pole or perch?

This converter is mostly designed for interpreting historical land records and may not be suitable for modern measurement requirements.
-
How do variations in arpent affect conversion?
-
Since the arpent varied by region and time, conversions may require additional adjustment based on local historical context to maintain accuracy.
