In English and related languages, several terms involving the words "great" or "gross" (possibly, from French: grosse thick) relate to numbers involving multiples of twelve (a dozen):
A gross refers to a group of 144 items (a dozen dozen).
A great gross refers to a group of 1728 items (a dozen gross).
A small gross or a great hundred refers to a group of 120 items (ten dozen).
A gross may be abbreviatied as "gr" or "gro".
The continued use of these numbers in measurement and counting represents a holdover of the duodecimal number system in modern usage 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.
