About these units

Foot (ft)

US & ImperialCurrent unit

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).

League (lea)

US & ImperialHistorical unit (no longer in standard use)

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.

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.

1 league = 4,828.032 meters (exactly).
