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).

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).
