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).

Score (score)

General & non-SITraditional unit (still used in some regions)

Twenty items. Seen in 'threescore years and ten' and 'four score and seven years ago'.

Score is a counting word for twenty, and it likely began as a notch. The Old Norse skor meant a notch or tally cut into a stick, and every twentieth mark was made larger, so the word came to mean twenty itself. English often pairs it with a number, as in threescore or fourscore. People also use scores loosely for a large, unspecified number.

Two famous passages keep the unit visible. In Psalm 90:10 of the King James Bible, the days of our years are threescore years and ten, which is 70, or fourscore, which is 80, if strength allows. And on November 19, 1863, Abraham Lincoln opened the Gettysburg Address with four score and seven years ago, meaning 87 years, which counts back to 1776 and the Declaration of Independence. A score of years is simply two decades.

1 score = 20 pieces (exactly).
