What is a nautical league (int.)?

An international nautical league is a historical maritime unit of length defined as three international nautical miles, equaling 5,556 metres, used primarily to express sea distances.

Why convert nautical leagues (int.) to Earth's polar radius?

This conversion helps integrate historical maritime distances with modern geodetic measurements used in mapping, satellite studies, and geospatial analysis.

Are the conversion values exact for all contexts?

No, the conversion uses idealized values and does not account for slight variations in Earth's shape or historical measurement inconsistencies.
