Is there a word for words like "dozen", "score", "gross" that refer to specific cardinal numbers?

I'd like to know whether the words that describe numerical quantities have a name to describe them as a group.

This would be similar to how onomatopoeia is a word to describe a group of words that all share the characteristic of actually sounding like the sound they are describing.

EDIT, note that my question is not asking the same question as at this link, because I'm asking for the word describing the group or category

English words for specific positive integers (e.g. dozen, score, gross, myriad)

Solution 1:

Along with numerals, and special-purpose words like some, any, much, more, every, and all, they're Quantifiers. Quantifiers are a kind of determiner and occur in many constructions with other determiners, like articles: e.g, two dozen or more than a score. If you want a special term for the words that describe numbers like these, you could call them lexical quantifiers, but then you'd have to explain what you meant because it isn't standard. — John Lawler

Quantifier has a nice entry in Lexico.

1.1 Grammar A determiner or pronoun indicative of quantity (e.g. all, both).

Solution 2:

Those words are counting units or units of amount, as contrasted to "units of measurement".

Example usage:

A dozen is a common counting unit. A counting unit is a convenient number that makes it easier to count objects. We often count doughnuts and eggs by dozens. Similarly, we count shoes and gloves in pairs. Table 1 gives examples of common counting units. Chemists, however, do not work with macroscopic (visible) objects like shoes and doughnuts. Instead, chemists are interested in microscopic entities: atoms and molecules. Since these entities are so small, chemists established their own practical counting unit called the mole.
