A specialization of quantity (q.v.). This is the collection of quantities that have a numeric component and could actually be used to measure something, as opposed to (say) merely ranking it on a scale. Arithmetic operations (such as addition and multiplication) can be performed on measurable quantities, as they can on purely numeric scalars (see numeric value).
Any quantity (that at least in principle could be) returned by a unit of measure (q.v.) function is a measurable quantity. In CycL, particular measurable quantities are usually represented as the result of applying a unit-of-measure function to a real number or pair of reals. For example, (meter 5) is the distance 5 meters.
For predicates that relate things to measurable quantities that characterize them, see measure.
Specializations of measurable quantity include distance, temperature, weight, and time. Other, broader specializations are one dimensional quantity, two dimensional quantity, and three dimensional quantity.
