What Is This Tool?
This tool allows you to convert lengths from furlongs, an imperial unit, to arpents, a historical French unit. It is designed to help interpret historical land measurements and cadastral records where these units were commonly used.
How to Use This Tool?
-
Enter the value in furlongs you wish to convert.
-
Select furlong as the input unit and arpent as the output unit.
-
Click convert to see the equivalent length in arpents.
-
Use the result to understand historical land measurements or legal documents.
Key Features
-
Converts between furlong (fur) and arpent units of length.
-
Reflects historical usage in land measurement and cadastral mapping.
-
Supports interpretation of old property descriptions and maps.
-
Browser-based and easy to use for legal, surveying, and genealogical research.
Examples
-
Convert 2 furlongs to arpents to get 6.875 arpents.
-

Common Use Cases
-
Interpreting distances in horse racing and racecourse descriptions.
-
Translating historical land and property measurements from imperial to French units.
-
Analyzing cadastral maps and land grants from French colonial regions like Quebec and Louisiana.
-
Support for legal and genealogical research involving old property descriptions.
Tips & Best Practices
-
Confirm the specific arpent definition used in your region or period, as it varies historically.
-
Use this tool for historical and legal research rather than scientific measurements.
-
Cross-check converted values with original records for accuracy in interpretations.
Limitations
-
The arpent's exact length varied by region and era, affecting conversion accuracy.
-
These units are not commonly used in modern engineering or scientific work.
-
Old records may contain inconsistent unit definitions, limiting precision.
Frequently Asked Questions
-
What is a furlong used for?
-
A furlong is an imperial unit of length historically used in horse racing, land measurements, and old surveying, equal to 220 yards or exactly 201.168 metres.
-
Where was the arpent commonly used?
-
The arpent was primarily used in France and French colonies like Quebec and Louisiana for land measurement and cadastral purposes.
-
