A league is a historical length unit formerly used for land and sea distances, commonly equal to about 3 statute miles or 3 nautical miles depending on type.

What is a chain (US survey)?

A chain (US survey) is a traditional unit equal to 66 US survey feet, historically used in U.S. land surveying and cadastral work.

Why is the conversion between league and chain important?

It helps interpret and convert older survey and navigation records into measurements compatible with modern surveying and mapping systems.
