League
A league is an old unit of distance that was commonly used in the past, especially for measuring distances on land or sea. Traditionally, one league equals about 3 miles or roughly 4.8 kilometers. The exact length of a league could vary by country and time period. It was often used by sailors and travelers to describe how far they had gone. Although the league is mostly obsolete today, it still appears in literature and historical contexts.
Link (US Survey)
The US survey link is a unit of length used in the United States for land surveying, defined as exactly 7.92 US survey inches. Since one US survey inch is slightly longer than the international inch (due to the US survey foot), the US survey link is approximately 0.201168 meters.
It is part of the US survey system, derived from Gunter’s chain, which is divided into 100 links per chain (66 US survey feet). Links are used to measure small distances in surveying and land measurement.
Key facts:
1 US survey link = 7.92 US survey inches
1 US survey link ≈ 0.201168 meters
100 links = 1 US survey chain (66 US survey feet)
25 links = 1 US survey rod (16.5 US survey feet)
Though the US survey units are being phased out, the US survey link still appears in historical land records and legal surveying documents.
