League (lea)
Three statute miles (4.828 km). Said to be roughly the distance a person could walk in an hour; the length varied widely across Europe.
1 league = 4,828.032 meters (exactly).
About the league
How far can a person walk in an hour? Roughly that question lies behind the league, which may once have approximated the answer. The Romans borrowed the idea from Gaul, calling it the leuga Gallica and fixing it at one and a half Roman miles, about 2.2 km. The word survives in several languages, yet the length it names has been anything from about 2.2 km to nearly 7.9 km depending on the country and the century.
In England the land league was most often three statute miles, which gives 4.83 km, or exactly 4,828.032 m, the figure used here. A medieval chronicle from Battle Abbey instead defined the English leuga as 7,680 feet. French lieues ranged from about 3.25 to 4.68 km, and a metric lieue of 4,000 m was legal from 1812 to 1840. The Spanish legua of about 5.57 km lasted in Latin America, where it also measured land area in early grants in Texas and New Mexico. No country defines it officially today.
