Oh a dozen predates the imperial system by a long way. From wiki because I’m a lazy…
The dozen may be one of the earliest primitive integer groupings, perhaps because there are approximately a dozen cycles of the Moon, or months, in a cycle of the Sun, or year. Twelve is convenient because it has a maximal number of divisors among the numbers up to its double, a property only true of 1, 2, 6, 12, 60, 360, and 2520.[1]
The use of twelve as a base number, known as the duodecimal system (also as dozenal), originated in Mesopotamia (see also sexagesimal). Twelve dozen (122 = 144) are known as a gross; and twelve gross (123 = 1,728, the duodecimal 1,000) are called a great gross, a term most often used when shipping or buying items in bulk. A great hundred, also known as a small gross, is 120 or ten dozen. Dozen may also be used to express a moderately large quantity as in “several dozen” (e.g., dozens of people came to the party).[2]
Varying by country, some products are packaged or sold by the dozen, often foodstuff (a dozen eggs).
Farm just down the road sells dozens for a dollar.
But I don’t really care for eggs, so I’m not seething so much as chuckling at the egg prices in the store.
This morning I passed a dozen for $6.
A farm just outside of my US town was selling eggs $5 for a dozen
Dozen is 12 ? Im not used to imperial units od measurements
