What is a mile (Roman)?

A mile (Roman) is an ancient Roman unit of length equaling 1,000 double steps or approximately 1,480 meters, used historically for measuring distances on roads and in military surveying.

What does the league measure?

A league is a historic unit of length used for land or sea distances, with its value commonly set as either about 3 statute miles or 3 nautical miles, varying by place and era.

Why are conversions between these units approximate?

Because the league's length varied historically by location and context and both units are not standard SI units, so exact equivalences are not consistent.
