What Is This Tool?
This converter transforms measurements from link (US survey), a traditional small length unit used in historic American land surveys, into inch (US survey), another legacy unit. It's ideal for interpreting old survey plats, cadastral mapping, and civil engineering projects involving historic data.
How to Use This Tool?
-
Enter the length value in link (US survey) unit you wish to convert.
-
Select 'link (US survey) [li]' as the from-unit and 'inch (US survey) [in]' as the to-unit.
-
Click the convert button to obtain the equivalent length in US survey inches.
-
Review the converted value for use in interpreting or updating survey data.
-
Use the result in cadastral, surveying, or civil engineering tasks requiring legacy data conversion.
Key Features
-
Converts link (US survey) units to inch (US survey) units based on established legacy definitions.
-
Supports interpretation of historical land survey and cadastral data.
-
Browser-based and easy-to-use interface ideal for engineers and surveyors.
-
Facilitates conversion for updating and reconciling old survey records with modern measurements.
-
Handles specialized units used in US land surveying and geodetic control.
Examples
-
Converting 5 link (US survey) results in 39.6 inch (US survey).
-
Converting 10 link (US survey) results in 79.2 inch (US survey).
Common Use Cases
-
Translating historic US land survey distances into smaller measurement units for detailed analysis.
-
Interpreting cadastral maps and boundary descriptions from legacy survey plats.
-
Reconciliation of old land survey data with modern civil engineering or land development projects.
-
Processing geodetic control points and land parcel records originally measured in US survey units.
-
Converting survey datasets between legacy units and metric or international standards.
Tips & Best Practices
-
Always verify the unit definitions when working with legacy survey records to ensure consistency.
-
Use this converter as part of a broader workflow for updating historic survey data to modern standards.
-
Be aware of minor differences between US survey and international units to avoid errors.
-
Consult original land survey documents for proper context before converting units.
-
Double-check conversions when mixing old survey data with metric or international foot measurements.
Limitations
-
Both link and inch (US survey) units are legacy measurements and not standard in modern surveying.
-
The US survey foot and inch differ slightly from international definitions, which may cause small discrepancies.
-
Historical measurement tolerances in old records may limit conversion precision.
-
This tool does not convert between survey units and metric or international units directly.
-
Users should validate converted data when used in official modern land measurement contexts.
Frequently Asked Questions
-
What is a link (US survey)?
-
The US survey link is a historical length unit equal to 1/100 of a Gunter's chain, approximately 0.66 US survey feet or 7.92 US survey inches, commonly used in US land surveying.
-
How does an inch (US survey) differ from a standard inch?
-
The US survey inch equals exactly 100/3937 meters, used in legacy US surveying, and slightly differs from the international inch definition.
-
Why convert between link and inch (US survey)?
-
Converting link to inch helps interpret and analyze historic land survey data by expressing measurements in smaller, more precise legacy units.
-
Can this tool be used for modern land measurement conversions?
-
No, this converter is designed for legacy US survey units and may not align with modern international or metric standards.
-
Is the US survey foot the same as the international foot?
-
No, the US survey foot and inch differ slightly from their international counterparts, which can cause minor variances.
