dimension

dimension is defined in Webster's Unabridged Dictionary (1913) with 4 senses. The full text of each entry is reproduced verbatim below.

Definitions

  1. 1.Extent; reach; scope; importance; as, a project of large dimensions.
  2. 2.(Math.) The degree of manifoldness of a quantity; as, time is quantity having one dimension; volume has three dimensions, relative to extension.
  3. 3.(Alg.) A literal factor, as numbered in characterizing a term. The term dimensions forms with the cardinal numbers a phrase equivalent to degree with the ordinal; thus, a2b2c is a term of five dimensions, or of the fifth degree.
  4. 4.pl. (Phys.) The manifoldness with which the fundamental units of time, length, and mass are involved in determining the units of other physical quantities. Thus, since the unit of velocity varies directly as the unit of length and inversely as the unit of time, the dimensions of velocity are said to be length ÷ time; the dimensions of work are mass × (length)2 ÷ (time)2; the dimensions of density are mass ÷ (length)3. Dimension lumber, Dimension scantling, or Dimension stock (Carp.), lumber for building, etc., cut to the sizes usually in demand, or to special sizes as ordered. -- Dimension stone, stone delivered from the quarry rough, but brought to such sizes as are requisite for cutting to dimensions given.
