Mathematics A geometric purpose that describes the distances between sets of things in a space.

Poetic meter.

A measure for anything; an easy method of deriving a quantitative dimension or approximation for otherwise qualitative phenomena (especially utilized in Software Engineering)

A measurement associated with "distance" between two things in certain metric room: it's a real-valued function d(x,y) between points x and y fulfilling listed here properties: (1) "positive definiteness": and , (2) "balance": , and (3) "triangle inequality": .

Same as metrics.

a decimal device of dimension of this metric system (centered on yards and kilograms and seconds)

a function of a topological room that offers, for almost any two things within the room, a value corresponding to the distance between them

something of relevant actions that facilitates the quantification of some certain characteristic
