What Is This Tool?
This tool allows users to convert measurements from the historic English unit link (li), traditionally used in land surveying, into kilometers (km), the standard unit for expressing distances at human and geographic scales.
How to Use This Tool?
-
Enter the numerical value in links (li) you want to convert.
-
Select 'link [li]' as the input unit and 'kilometer [km]' as the output unit.
-
Click the convert button to see the equivalent distance in kilometers.
Key Features
-
Converts length values from link (li) to kilometer (km).
-
Supports interpretation of historical land measurement units.
-
Provides simple multiplication-based conversion using a fixed rate.
-
Useful for relating old cadastral records to modern metric systems.
Examples
-
50 link = 50 × 0.000201168 km = 0.0100584 km
-
1000 link = 1000 × 0.000201168 km = 0.201168 km
Common Use Cases
-
Surveying with Gunter's chain in historic land measurement.
-
Interpreting measurements from old deeds and cadastral documents.
-
Reconstructing historical property boundaries and maps.
-
Converting historic distances into modern metric units for analysis.
Tips & Best Practices
-
Ensure accuracy by confirming the original historic measurement quality.
-
Be cautious with very small decimal values resulting from conversion to kilometers.
-
Use the tool to complement research in historical surveying and geodesy.
Limitations
-
The link is a historic unit no longer in common use.
-
Conversion accuracy depends on the precision of original measurements.
-
Small values in kilometers may require careful handling in calculations.
Frequently Asked Questions
-
What is a link (li) unit?
-
A link is a historic English length unit used in surveying, equal to 1/100 of Gunter's chain and approximately 0.201168 metres.
-
How is the link related to kilometers?
-
One link equals 0.000201168 kilometers, allowing conversion between historic and modern units of length.
-
In what fields is this conversion useful?
-
It is useful in historical surveying, cadastral record analysis, geodesy, and reconstructing historic property boundaries.
Key Terminology
-
Link [li]
-
A historic English unit of length used in surveying, equal to 1/100 of Gunter's chain and about 0.201168 metres.
-
Kilometer [km]
-
An SI derived unit of length equal to 1,000 metres, commonly used for expressing distances on human and regional scales.
-
Gunter's chain
-
A historic measuring chain used in surveying, of which one link is 1/100th part.
