Noun

A measure for something; a means of deriving a quantitative measurement or approximation for otherwise qualitative phenomena (esp. used in Software Engineering)
A measurement of the "distance" between two points in some metric space: it is a function d(x,y) between points x and y satisfying the following properties: (1) "positive definiteness": $d(x,y) \ge 0$ and $d(x,y) = 0 \mbox{ iff } x=y$ , (2) "symmetry": $d(x,y) = d(y,x)$ , and (3) "triangle inequality": $d(x,y) \le d(x,z) + d(z,y)$ .
