Definition
Quantity. Property of a phenomenon, body, or substance, to which a number can be assigned with respect to a reference. A counted number of non-monetary units possibly including fractions.
A quantity as defined here is said to be a "scalar" as distinct from a "vector." However, a vector or a tensor whose components are quantities is also considered to be a quantity.
Examples
A second, a kilogram, a joule, a meter. These are quantities in a general sense, which is what is meant here by quantity.
