What is a nautical league (int.)?

It is a historical maritime unit equal to three international nautical miles or 5,556 meters, used mainly in older nautical contexts.

What is a chain [ch] used for?

A chain is a traditional surveying unit of length, often used in cadastral surveying and interpreting historical land measurements.

Why convert nautical leagues to chains?

Converting helps translate historical maritime distances into land measurement units useful for archival research, land registration, and survey restoration.
