About these units
Roman League (leuga)
One and a half Roman miles (7,500 Roman feet), about 2.22 km. Used in Gaul and later across the empire for longer distances.
Gaul, not Rome, gave this unit its name. The Latin leuga or leuca came from a Celtic measure of the Gauls that the Romans adopted, and it is the ancestor of the later European league. It may originally have approximated the distance a person could walk in an hour, though that is a suggestion rather than a documented definition.
In Roman terms it was fixed at one and a half Roman miles, or 7,500 Roman feet, which comes to about 2.22 km. Under Septimius Severus this Gallo-Roman league replaced the mile as the official road distance in the Gallic and Germanic provinces. Even so, its practical length varied by region and period, so 2,220 m is a convention based on the 296 mm foot rather than a measured constant.
Later leagues strayed far from the Roman original. Medieval and later values ran from about 2.2 km up to nearly 8 km, with the English league taken as three miles, the Spanish common league near 5.57 km, and a French metric lieue set at exactly 4 km in 1812. No country officially uses it now, though Jules Verne's famous title keeps the word familiar.
1 Roman league = 2,220 meters (approximately).

Mile (mi)
5,280 feet or 1,760 yards, exactly 1,609.344 meters. This is the statute (international) mile used on US and UK roads.
A thousand paces gave the mile its name. It descends from the Latin mille passus, the Roman mile, by way of Old English mil and Middle English myle. For centuries after Rome, miles of many lengths coexisted; a sixteenth-century Mercator map, for example, shows small, medium and large Flemish miles on a single scale bar. The English statute mile was fixed by an Act of Parliament under Elizabeth I in 1593, which declared that a mile contains eight furlongs, or 5,280 feet.
The 1959 international yard and pound agreement made that mile exactly 1,609.344 meters. A slightly longer US survey mile, about 1,609.347 meters, lingered in American land surveys and was slated for retirement from 1 January 2023. Today the mile is the road unit of the United Kingdom, the United States, Liberia and Myanmar, along with several territories such as the Bahamas, Belize, Guam and the US Virgin Islands. In Canada it survives chiefly in rail transport and horse racing.
1 mile = 1,609.344 meters (exactly).
