Definition
Quantity. Property of a phenomenon, body, or substance, to which a number can be assigned with respect to a reference
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.
Example
second, kilogram, joule, meter. These are quantities in a general sense, which is what is meant here by quantity.
Issues and Challenges
The term quantity is used here to refer to the abstraction of the properties - the amount of measurable stuff that can be compared between particular quantities. The height of the something refers to a particular quantity; 555 ft 5 inches refers to a quantity value.
