What Is This Tool?
This unit converter allows you to transform length measurements from the UK nautical mile (historically called the Admiralty nautical mile) into the US survey link, a historical subdivision unit used in land surveying. It is useful for interpreting legacy maritime and cadastral records.

Common Use Cases
-
Interpreting distances on historical UK Admiralty maritime charts
-
Converting legacy British maritime measurements into US surveying units
-
Working with historic cadastral mapping and land survey data in the US
-
Reconciling measurements for legal or engineering projects involving legacy records
Tips & Best Practices
-
Check the context to confirm if the UK nautical mile or the international nautical mile applies
-
Use this tool primarily for archival, legal, or historical analyses due to unit rarity today
-
Verify measurement standards when mixing UK and US survey units in data
Limitations
-
UK nautical mile is slightly longer than the international nautical mile, so direct comparisons require care
-
US survey link is a historic unit infrequently used in modern measurements
-
Differences in feet standards between UK and US survey feet affect precision
Frequently Asked Questions
-
What is the UK nautical mile used for?
-
It was historically defined for maritime navigation in the UK and appears in old Admiralty charts and logs.
-
Why convert measurements from UK nautical miles to US survey links?
-
This conversion helps reconcile historical maritime distances with detailed land survey measurements used in the US.
-
Are these units commonly used today?
-
Both units are mostly historical and primarily relevant for archival, legal, and historical research rather than current practice.
