  Dimension  \Di*men"sion\,  n.  [L.  dimensio,  fr  dimensus  p.  p.  of 
  dimetiri  to  measure  out  di-  =  dis-  +  metiri  to  measure:  cf 
  F.  dimension.  See  {Measure}.] 
  1.  Measure  in  a  single  line  as  length,  breadth,  height, 
  thickness,  or  circumference;  extension;  measurement;  -- 
  usually,  in  the  plural,  measure  in  length  and  breadth,  or 
  in  length,  breadth,  and  thickness;  extent;  size;  as  the 
  dimensions  of  a  room  or  of  a  ship;  the  dimensions  of  a 
  farm,  of  a  kingdom. 
 
  Gentlemen  of  more  than  ordinary  dimensions.  --W. 
  Irving. 
 
  {Space  of  dimension},  extension  that  has  length  but  no 
  breadth  or  thickness;  a  straight  or  curved  line 
 
  {Space  of  two  dimensions},  extension  which  has  length  and 
  breadth,  but  no  thickness;  a  plane  or  curved  surface. 
 
  {Space  of  three  dimensions},  extension  which  has  length, 
  breadth,  and  thickness;  a  solid. 
 
  {Space  of  four  dimensions},  as  imaginary  kind  of  extension, 
  which  is  assumed  to  have  length,  breadth,  thickness,  and 
  also  a  fourth  imaginary  dimension.  Space  of  five  or  six 
  or  more  dimensions  is  also  sometimes  assumed  in 
  mathematics. 
 
  2.  Extent;  reach;  scope;  importance;  as  a  project  of  large 
  dimensions. 
 
  3.  (Math.)  The  degree  of  manifoldness  of  a  quantity;  as  time 
  is  quantity  having  one  dimension;  volume  has  three 
  dimensions,  relative  to  extension. 
 
  4.  (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 
  a^{2}b^{2}c  is  a  term  of  five  dimensions,  or  of  the  fifth 
  degree. 
 
  5.  pl  (Phys.)  The  manifoldness  with  which  the  fundamental 
  units  of  time,  length,  and  mass  are  involved  in 
  determining  the  units  of  other  physical  quantities. 
 
  Note:  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  [divby] 
  time;  the  dimensions  of  work  are  mass  [times] 
  (length)^{2}  [divby]  (time)^{2};  the  dimensions  of 
  density  are  mass  [divby]  (length)^{3}. 
 
  From  WordNet  r  1.6  [wn]: 
 
  dimension 
  n  1:  a  measure  of  the  size  of  something  in  a  particular  direction 
  esp  length  or  width  or  height 
  2:  a  construct  whereby  objects  or  individuals  can  be 
  distinguished;  "self-confidence  is  not  an  endearing 
  property"  [syn:  {property},  {attribute}] 
  3:  one  of  three  coordinates  that  determine  a  position  in  space 
  4:  magnitude  or  extent;  "a  building  of  vast  proportions"  [syn: 
  {proportion}] 
  v  1:  indicate  the  dimensions  on  "These  techniques  permit  us  to 
  dimension  the  human  heart" 
  2:  shape  or  form  to  required  dimensions
