chopine

1

In France, an old and widespread unit of liquid capacity, first recorded in the 13ᵗʰ century, 23.475 cubic pouces (of Paris), about 0.465 liters.

In the Système Usuel, 1812-1840, the chopine was set = 0.5 liters (about 1.06 U.S. liquid pints), and the term is still used in this sense. Two chopines make a pinte. The chopine was sometimes called a setier, but see setier for that term's other meanings (e.g., 100 liters of dry capacity in the Système Usuel).

From medieval times the chopine has been especially associated with wine, and in France the word now usually means a drink of wine.

In England, perhaps a unit of liquid capacity in the 14ᵗʰ century. Almost all of the citations we have seen actually describe use in France or Scotland, yet the city of London forbade its use in 1310 (see here), which indicates some use. Wright, though marking it as French, says it was in use in Northmberland, on the Scottish border. That suggests the influence of the Scottish word rather than French.
