What Is This Tool?
This tool converts length values from chain (US survey) to link (US survey), units traditionally used in U.S. land surveying. It helps interpret and translate legacy survey measurements for accurate mapping and boundary documentation.
How to Use This Tool?
-
Enter the length value in chain (US survey) units
-
Select chain (US survey) as your input unit and link (US survey) as your output unit
-
Click convert to see the measurement expressed in links (US survey)
Key Features
-
Converts chain (US survey) to link (US survey) based on historical land surveying units
-
Supports legacy unit conversions relevant to cadastral and land-transfer projects
-
Browser-based and easy to use without requiring specialized software
Examples
-
Convert 1 chain (US survey) to links (US survey) to get 100 links
-
Convert 0.5 chain (US survey) to links, resulting in 50 links
Common Use Cases
-
Interpreting distances in historical U.S. land deeds and cadastral surveys
-
Converting legacy survey data for mapping and Geographic Information Systems (GIS)
-
Reconciling modern land measurements with older survey records in civil engineering
Tips & Best Practices
-
Ensure clarity on whether US survey feet or international feet are being referenced
-
Use this tool when working with historical cadastral documents and mapping projects
-
Cross-check conversions with original survey records for the best accuracy
Limitations
-
Units are legacy measurements relevant mainly to historical US land surveying
-
Potential confusion may arise between US survey feet and other foot definitions
-
Conversion accuracy depends on historical survey context and variation
Frequently Asked Questions
-
What is the conversion rate from chain (US survey) to link (US survey)?
-
One chain (US survey) equals 100 links (US survey).
-
What are these units used for?
-
They are traditional units used historically in U.S. land surveying, cadastral mapping, and property boundary descriptions.
-
Can this tool be used for modern surveying measurements?
-
This tool is intended for interpreting legacy measurements and may not apply directly to modern standardized units.
Key Terminology
-
Chain (US survey) [ch]
-
A traditional unit of length equal to 66 US survey feet, divided into 100 links, used historically in American land surveying.
-
Link (US survey) [li]
-
A subdivision of a Gunter's chain equal to 1/100 of a chain or 0.66 US survey feet, used in historical land measurement.
-
Gunter's chain
-
A measuring device used in surveying that defines the length of one chain (US survey) as 66 US survey feet.
