Metric \Met"ric\, a. [L. metricus, Gr. ?: cf. F. m['e]trique.
   See {Meter} rhythm.]
   1. Relating to measurement; involving, or proceeding by,
      measurement.

   2. Of or pertaining to the meter as a standard of
      measurement; of or pertaining to the decimal system of
      measurement of which a meter is the unit; as, the metric
      system; a metric measurement.

   {Metric analysis} (Chem.), analysis by volume; volumetric

   {Metric system}, a system of weights and measures originating
      in France, the use of which is required by law in many
      countries, and permitted in many others, including the
      United States and England. The principal unit is the meter
      (see {Meter}). From this are formed the are, the liter,
      the stere, the gram, etc. These units, and others derived
      from them, are divided decimally, and larger units are
      formed from multiples by 10, 100, 1,000, and 10,000. The
      successive multiplies are designated by the prefixes,
      deca-, hecto-, kilo-, and myria-; successive parts by
      deci-, centi-, and milli-. The prefixes mega- and micro-
      are sometimes used to denote a multiple by one million,
      and the millionth part, respectively. See the words formed
      with these prefixes in the Vocabulary. For metric tables,
      see p. 1682.
