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).

Foot (ft)
12 inches. Defined as exactly 0.3048 meters. Still the standard unit for height, altitude in aviation and room dimensions in the US and UK.
Human anatomy supplied the idea: an adult foot is roughly 15 percent of body height. Ancient cultures turned that into standards, but not the same one. The Greek pous was about 302 mm, the standard Roman pes about 295.7 mm, and a Harappan foot of about 335 mm has been reported from the Indus Valley. Historically, a foot fell somewhere between about 250 and 335 mm. Charlemagne tried to standardize units around 790 with little lasting success, and in 1593 English law fixed the statute mile at 5,280 feet.
The modern foot dates from the 1959 International Yard and Pound Agreement, which defined the yard as exactly 0.9144 meter and so the foot as exactly 0.3048 meter; the UK adopted it on 1 January 1964. The US survey foot, defined in 1893 as 1200/3937 meter, was deprecated on 31 December 2022. Feet remain in everyday use for height and rooms in the US, and ISO shipping containers are defined in them. Aviation altitudes use them too: flight level 330 means 33,000 feet.
1 foot = 0.3048 meters (exactly).
