Kvantitet

Kvantitet is a noun used in several European languages, notably Swedish, Norwegian, and Danish, to denote quantity or amount. In these languages, kvantitet refers to how much of something exists and is often contrasted with kvalitet, which means quality. In Dutch, the analogous term is quantiteit, though the everyday word for amount is hoeveelheid. The word derives from Latin quantitas, via French quantité, and shares cognates with German Quantität and other Romance and Germanic forms.

In scientific contexts, a physical quantity is a property that can be measured, such as length, mass, or time. Quantities may be scalar, having only magnitude, or vector, having direction in addition to magnitude. Quantities are expressed in units and are subject to dimensional analysis and unit conventions, most notably the International System of Units (SI).

In economics and commerce, quantity refers to the amount of goods or services exchanged or held, such as the quantity demanded or the quantity in inventory. Statisticians address quantities in data as measures or observations, distinguishing them from qualitative attributes.

In everyday language, kvantitet is used to describe numerical extents, totals, or counts, depending on the language context. The term is not identical across languages, and usage can vary by domain. Related terms include quantity, amount, and magnitude.
