About these units

Yard (yd)

US & ImperialCurrent unit

3 feet or 36 inches, exactly 0.9144 meters. Used for sports fields, fabric and short distances in the US and UK.

Yard descends from the Old English gerd or gyrd, meaning a branch, stave or measuring rod. It first appears in the late seventh-century laws of Ine of Wessex, though there it names a tax unit, the yardland. Around 959 to 963 King Edgar ordered that the measure held at Winchester be used throughout his realm, the earliest record of a prototype. A story that Henry I fixed the yard as the distance from his nose to his thumb is later folklore, and the true origin, whether pace, cubit or waist, remains speculative.

Britain defined the Imperial Standard Yard in 1824 as the distance between two marks on a brass rod at 62 degrees Fahrenheit. A fire in 1834 damaged the standard, a replacement was made in 1845, and the Weights and Measures Act 1855 recognized it. The 1959 international agreement then fixed the yard at exactly 0.9144 meter. Today it measures American and Canadian football fields, association football pitches and cricket pitches, appears on UK road signs for short distances, and is still used to sell fabric in the US and UK.

Roman League (leuga)

Ancient RomanHistorical unit (no longer in standard use)Approximate value

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).
