What Is This Tool?
This unit converter allows you to translate measurements from the US survey link, a historical small-length unit, into kilometers, the standard metric unit for distance. It is designed to help with interpreting legacy land survey data and integrating it with contemporary geospatial formats.
How to Use This Tool?
-
Enter the measurement value in links (US survey) you want to convert.
-
Select the unit 'link (US survey) [li]' as the input unit and 'kilometer [km]' as the output unit.
-
Click the convert button to receive the equivalent distance in kilometers.
-
Use the result to interpret or process distances within modern geographic or engineering applications.
Key Features
-
Converts the US survey link (li), a small subdivision of Gunter's chain, into kilometers (km).
-
Supports conversion of historic land surveying lengths to modern metric measurements.
-
Browser-based, easy-to-use interface for quick unit translations.
-
Enables compatibility between legacy cadastral records and current mapping systems.
Examples
-
50 links (US survey) equals 0.01005842 kilometers.
-
1,000 links (US survey) equal 0.2011684 kilometers.
Common Use Cases
-
Interpreting distances recorded in historic US land survey plats and deeds.
-
Cadastral mapping and boundary descriptions involving legacy survey data.
-
Civil engineering or land transfer projects that reconcile older survey records with modern measurements.
-
Converting fine-scale historic land measurements into metric units for compatible mapping.
Tips & Best Practices
-
Ensure survey records specify the use of US survey feet to avoid confusion with international feet definitions.
-
Use this conversion when working with older cadastral maps to accurately integrate data into metric-based GIS systems.
-
Be mindful of the deprecated status of the link unit and verify when precision is critical.
Limitations
-
The link (US survey) is a deprecated, non-SI unit mainly relevant to historic data.
-
Converting may introduce rounding errors due to the small scale of the link compared to kilometers.
-
Accuracy depends on the quality of legacy survey records and differing feet definitions.
Frequently Asked Questions
-
What is a link (US survey)?
-
A link (US survey) is a historical unit of length equal to 1/100 of a Gunter's chain, approximately 0.201168 meters, used mainly in US land surveying.
-
Why convert links (US survey) to kilometers?
-
Converting links to kilometers helps translate historic survey measurements into modern metric units for mapping, planning, and legal purposes.
-
Can I use this conversion for precise modern engineering work?
-
While useful for interpretation, the link is deprecated and may introduce rounding errors, so verify precision requirements carefully.
