What is a link (US survey)?

A link (US survey) is a historical length unit equal to 1/100 of a Gunter's chain, used in US land surveys. One link is approximately 0.201168 meters.

How is the UK nautical mile defined?

The UK nautical mile, or Admiralty nautical mile, is exactly 6,080 feet or 1,853.184 meters, slightly longer than the international nautical mile.

Why convert between link (US survey) and UK nautical mile?

Converting these units helps reconcile and interpret legacy land survey data with maritime navigation records, especially when working with historical US and UK measurements.
