What Is This Tool?
This tool allows users to convert length values from the Link (li), a historic English surveying unit, to the UK Nautical mile (NM (UK)), traditionally used in maritime contexts. It facilitates the interpretation and comparison of old surveying and nautical measurements with modern units.
How to Use This Tool?
-
Enter the length value in Links [li] you wish to convert.
-
Select Link [li] as the input unit and Nautical mile (UK) [NM (UK)] as the output unit.
-
Click convert to view the equivalent distance in UK Nautical miles.
Key Features
-
Converts between Link (li) and UK Nautical mile (NM (UK)) accurately.
-
Includes historical unit definitions for context and clarity.
-
Supports archival and maritime measurement conversion needs.
Examples
-
100 Links [li] equals 0.01085526 Nautical miles (UK) [NM (UK)].
-
500 Links [li] equals 0.0542763 Nautical miles (UK) [NM (UK)].
Common Use Cases
-
Surveying historic land properties using Gunter's chain measurements.
-
Interpreting distances on older UK Admiralty maritime charts.
-
Reconciling old cadastral and navigational records with modern units.
Tips & Best Practices
-
Verify whether your data requires the UK or international nautical mile for accuracy.
-
Use this tool primarily for historical and archival research purposes.
-
Cross-check converted values when interpreting old documents to accommodate measurement variability.
Limitations
-
Link (li) is a rarely used historic unit mostly relevant in archival contexts.
-
Differences in nautical mile definitions can affect conversion accuracy.
-
Small conversion factors and historic measurement variability may impact precision.
Frequently Asked Questions
-
What is a Link (li) in length measurement?
-
The Link (li) is a historic English unit of length used in surveying, equal to 1/100 of Gunter's chain, approximately 0.201168 metres.
