Metric or metrical may refer to:

Measuring

Metric system, an internationally adopted decimal system of measurement
An adjective indicating relation to measurement in general, or a noun describing a specific type of measurement

Mathematics

In mathematics, metric may refer to one of two related, but distinct concepts:

A function which measures distance between two points in a metric space
A metric tensor, in differential geometry, which allows defining lengths of curves, angles, and distances in a manifold

Natural sciences

Metric tensor (general relativity), the fundamental object of study in general relativity, similar to the gravitational field in Newtonian physics
Senses related to measurement:
- Metric system, an internationally adopted decimal system of measurement
- Metric units, units related to a metric system
- International System of Units, or Système International (SI), the most widely used metric system
METRIC, a model that uses Landsat satellite data to compute and map evapotranspiration (ET) in climatology/meteorology

Engineering and business

The word metric is often used to mean a descriptive statistic, indicator, or figure of merit used to describe or measure something quantitatively, including:

Performance indicator, a measure of an organization's activities and performance
Metrics (networking), the properties of a communication path used by a router to make routing decisions
Software metric, a measure of some property of a piece of software or its specifications
Reuse metrics, a quantitative indicator of an attribute for software reuse and reusability
Search engine optimization metrics, indicators of a website's organic search potential

Music

Alex Metric (born 1984), British musician, DJ and producer
Metric (band), a Canadian rock band founded in Toronto, Ontario

Other uses

Metre (poetry), the rhythmic structure of poetry
Font metrics, properties describing the overall shape of a font

-In [[mathematics]], a '''metric''' (also called '''distance metric''') is an abstraction of the notion of ''distance''; it is used to define [[metric space]]s. The article on [[metric space]]s contains a detailed discussion of the topic.

-In [[music]], ''metric'' and ''metrical'' refer to [[meter (music)]]. '''Metric structure''' includes meter, [[tempo]], and all [[rhythm]]ic aspects which produce temporal regularity or structure, against which the foreground details or [[durational pattern]]s are projected (DeLone et. al.

-'''Metric level'''s may be distinguished. The [[beat level]] is the metric level at which pulses are heard as the basic time unit of the piece. Faster levels are [[division level]]s, and slower levels are [[multiple level]]s. (DeLone et. al. (Eds.), 1975, chap. 3).
