About these units

Hundred (100)

General & non-SICurrent unit

One hundred.

The English word hundred descends from Old English hundred and, further back, from a Proto-Germanic compound that joined the old root for 100 with a word meaning count or row. For much of history it did not always mean 100. Old Norse counted large numbers in twelves of tens, and medieval England used a long hundred of 120 beside the short hundred of 100. Around 1300 the Assize of Weights and Measures had both in play: a hundred kippers or a hundred ells of hemp canvas or linen meant 120, while a hundred fresh herring meant 100.

The word also named a historical subdivision of southern English counties, notionally 12,000 acres. Today a hundred is simply ten tens, five score, or a tenth of a thousand, and the SI prefix hecto stands for 10². The long hundred faded as Arabic numerals, which rely on base 10, spread from the 14th century onward.

1 hundred = 100 pieces (exactly).

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).
