In English and related languages, several terms involving the words "great" or "gross" (possibly, from French: grosse thick) relate to numbers involving multiples of exponents of twelve (dozen):

  • A gross refers to a group of 144 items (a dozen dozen or a square dozen).[1][2]
  • A great gross refers to a group of 1728 items (a dozen gross or a cubic dozen).[1][2]
  • A small gross[3] or a great hundred[4] refers to a group of 120 items (ten dozen).

A gross may be abbreviated as "gr" or "gro".

The continued use of these numbers in measurement and counting represents a continuation of the tradition of the duodecimal number system in everyday life[5] and has encouraged groups such as the Duodecimal Society of America to advocate for a wider use of such a numbering system in place of decimal.[6][7]
