quantity
Focuses on the measurable aspect of an object or substance. It is a clinical, objective term that strips away subjective value or character, prioritizing 'how much' over 'how good'. In scientific and mathematical contexts, it serves as a technical designation for any property that can be expressed numerically, creating a sharp dichotomy between quantity (number) and quality (nature). When used in the phrase "in quantity," the word shifts from a neutral measurement to a connotation of bulk or mass production, often implying an industrial scale where volume is more important than individual precision.
Countable when referring to a specific measurable amount ('a small quantity of salt') or a mathematical property ('a vector quantity'). Uncountable when used in the phrase 'in quantity' to describe producing things in bulk.
