About these units

Gross (gr)

US & ImperialCurrent unit

Twelve dozen, 144 items. Still used when buying items such as pencils or buttons in bulk.

A gross is twelve dozen, 144 items, and the name is literally a large dozen: the term dates from the early 15th century and comes from the Old French grosse douzaine. Its plural is gross, as in three gross of screws.

Its structure is purely duodecimal. A gross is 12 dozens, 24 half dozens, or 72 pairs, and the step above it, the great gross, is 12 gross. Related terms include the small gross, which is 120. The larger groupings in this family are mainly used when buying or shipping in bulk, and the Dozenal Society of America promotes wider use of such terms as part of its case for counting in base 12.

1 gross = 144 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.
