A league is a unit of length (or, rarely, area). It was long common in Europe and Latin America, but it is no longer an official unit in any nation. The league most frequently refers to the distance a person or a horse can walk in an hour. However, the league had many different values, as can be seen below.
In English usage over the past couple of centuries or so, the league was most often considered to be 3 miles, This was about 4.8 km if referring to the statute (land) mile (now 1609.344 m, but varying slightly through history) or about 5.6 km if referring to the nautical mile (1852 m). However, English usage also included any of the other leagues mentioned below (e.g., in discussing the Treaty of Tordesillas).
The league was used in Ancient Rome, defined as 1.5 Roman miles (7,500 Roman feet, 2.2 km, 1.4 mi.). The origin is the "leuga gallica" (also: leuca Gallica), the league of Gaul.
The Argentinian league (legua) is 5.572 km (3.462 mi) or 6,666 varas: 1 vara is 0.83 m (33 in).
