About these units

Dozen (doz)

US & ImperialCurrent unit

Twelve items. Eggs, rolls and many goods are still sold by the dozen.

Dozen entered English from Old French douzaine, a group of twelve, built from douze, which comes from Latin duodecim, plus a suffix that makes a collective. Twelve earned its popularity partly by dividing evenly: it splits into halves, thirds, quarters, and sixths, which helps when sharing goods. One suggestion is that the roughly dozen lunar months in a solar year made twelve one of the earliest groupings.

Even in a decimal age, dozens persist in commerce, often for foods such as eggs. Larger multiples extend the system by twelves: a gross is 12 dozen, or 144, and a great gross is 12 gross, or 1,728. The idiom six of one, half a dozen of the other uses the unit to say two options come to the same thing. Twelve also gave English the baker's dozen, which adds one more.

1 dozen = 12 pieces (exactly).

Piece (pc)

General & non-SICurrent unit

A single item.

Piece is the plain unit for counting individual items, with no grouping implied. The word reached English from Old French piece, which came from Late Latin pecia or petia, meaning a fragment or a parcel of land. Its ultimate origin is uncertain, though Wiktionary notes a possible Gaulish source. It displaced the native Old English styce, which meant the same kind of thing.

Wiktionary defines it as a single item belonging to a class of similar items, and the word turns up in compounds such as by the piece, piece rate, and piecework. Every other counting unit in this family is just a fixed number of pieces: a pair is 2, a dozen 12, a gross 144, and a great gross 1,728. Treating the piece as the base is what lets any of them convert into any other by simple multiplication or division.

The piece is the reference unit for counting & quantity on this site.
