About these units
Pair (pr)
Two items.
Pair comes from Old French paire, which grew out of Latin paria, the neuter plural of par, meaning equal. German Paar and Dutch paar are relatives of the same word. The core idea is two matching things taken together, as in a pair of shoes or gloves.
English also uses pair for single objects built from two connected parts. Scissors, spectacles, trousers, and jeans are plural-only nouns, so a counting word is needed: you say a pair of scissors or several pairs of jeans. That makes the unit slightly slippery. Six pairs of socks is 12 socks, but six pairs of scissors is only six objects. The word has other senses too, such as two people in a relationship or two cards of equal rank in poker, but as a quantity of loose items it is always two.
1 pair = 2 pieces (exactly).

Gross (gr)
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).
