What Is This Tool?
This tool converts measurements from millimeters (mm), a precise metric unit, to the US survey link (li), a historic land surveying unit. It helps users work with legacy cadastral records and integrate modern data with traditional units.
How to Use This Tool?
-
Enter the length value in millimeters you want to convert.
-
Select the millimeter as the original unit and link (US survey) as the target unit.
-
Click the convert button to get the result in US survey links.
Key Features
-
Converts length values from millimeters to US survey links accurately based on defined conversion rates.
-
Supports historical and modern measurement integration for land surveying and civil engineering.
-
Browser-based and easy to use with no installation required.
Examples
-
100 mm equals approximately 0.49709596 li
-
500 mm equals approximately 2.4854798 li
Common Use Cases
-
Converting precise metric dimensions to links for interpreting historical land survey documents.
-
Working on cadastral maps requiring both modern and legacy unit measurements.
-
Civil engineering projects that involve reconciling recent surveys with old land records.
Tips & Best Practices
-
Verify unit selection before conversion to ensure accuracy.
-
Use this conversion for legacy data analysis rather than contemporary surveying.
-
Cross-check converted values with historical records when possible.
Limitations
-
The link (US survey) is mostly a historic unit and has limited modern usage.
-
Conversions may involve rounding differences when switching between very small and larger units.
-
Not suitable for precision measurements in current engineering projects.
Frequently Asked Questions
-
What is a millimeter used for?
-
A millimeter measures small distances and is used in engineering, science, and precise dimensioning like mechanical drawings and 3D printing.
-
Where is the US survey link commonly used?
-
The US survey link is used mainly in the United States for historical land surveying, cadastral mapping, and interpreting legacy survey data.
-
Why convert millimeters to survey links?
-
Converting allows modern metric measurements to align with historic land surveying records that use the link unit, facilitating land boundary and cadastral work.
Key Terminology
-
Millimeter [mm]
-
An SI derived unit of length equal to one thousandth of a meter, used for precise small-scale measurements.
-
Link (US survey) [li]
-
A historic unit of length used in US land surveying equal to one hundredth of a Gunter's chain or approximately 0.201168 meters.
-
Gunter's chain
-
A measurement length of 66 US survey feet used historically in land surveying to define the length of one chain.
