About these units

Inch (in)

US & ImperialCurrent unit

1/12 of a foot. Defined as exactly 25.4 millimeters since 1959, when the US and Commonwealth countries agreed a common international inch.

Latin uncia, meaning one-twelfth, is the root of both inch and ounce, and it passed into Old English as ynce. Roman measurers divided their foot into twelve unciae, and the English inch kept that twelfth. After 1066 an inch was reckoned as three barleycorns, and a 1324 statute attributed to Edward II spelled out the definition as three grains of barley, dry and round, placed end to end lengthwise. For centuries the inch was simply a twelfth of a foot, or a thirty-sixth of a yard, and the US and UK each kept their own copy of the standard yard.

Those copies differed slightly until the 1959 international agreement fixed the yard at exactly 0.9144 meter, which made the inch exactly 25.4 millimeters. The US adopted it in 1959 and the UK ratified it in 1963, effective 1964. Today the inch is still the customary unit in the United States and Canada, and the UK keeps it on road signs. Worldwide it also names display diagonals, wheel rims, tire codes and pipe sizes.

1 inch = 0.0254 meters (exactly).

Lieue (Paris League) (lieue)

French (Ancien Régime)Historical unit (no longer in standard use)

2,000 toises, about 3.898 km: the Paris league of 1674. The later post league (lieue de poste, 1737) was longer, at 2,200 toises or about 4.288 km.

Lieue descends from the Celtic league that the Romans adopted as the leuga. The Gallic version, about one and a half Roman miles, replaced the Roman mile as the official road distance in Gaul and Germania under Septimius Severus. In France the word later covered several different distances rather than one.

The figure used here, about 3,898 metres, is 2,000 toises, which Wikipedia's article on traditional French units calls the Paris league of 1674. The lieue de poste, which measured stages on the royal coach and mail routes, was set at 2,200 toises in 1737, about 4.288 kilometres. Wikipedia's league article lists the post league at the shorter 3,898 metres, so its two articles disagree about which league carried that name.

Other French leagues ranged from 10,000 to 14,400 pieds, or roughly 3.25 to 4.68 kilometres. The metric lieue of exactly 4,000 metres was used in the customary system between 1812 and 1840. Since the unit was never standardized, any conversion to kilometres should name which lieue is meant.

1 lieue (Paris league) = 3,898.07262 meters (approximately).
