metric

Of or relating to the metric system of measurement.

Of or relating to measurement by meters or by metrics.

Of or relating to the meter of a piece of music.

Of or relating to distance.

A way to measure something; a means of deriving a quantitative measurement or approximation for otherwise qualitative phenomena (especially used in engineering).

A function which satisfies a particular set of formal conditions, created to generalize the notion of the distance between two points. Formally, a real-valued function d on M×M, where M is a set, is called a metric if (1) d(x,y)=0 if and only if x=y, (2) d(x,y)=d(y,x) for all pairs (x,y), and (3) d obeys the triangle inequality.

A metric tensor.

Ellipsis of metric system.

To measure or analyse statistical data concerning the quality or effectiveness of a process.
