===Meaning===
[[Decimetres Cubed]] (dm<sup>3</sup>) are a [[unit]] of [[Volume (Space)|volume]] that is 1000 times smaller than the [[SI Unit]] of the [[Metres Cubed|metres cubed]].
===About Decimetres Cubed===
: '''Decimetres Cubed''' are shortened to dm<sup>3</sup> with with a lower case d and a lower case mand an [[indices]] of 3.
: A '''decimetre cubed''' is the [[Volume (Space)|volume]] of a [[cube]] with sides of 10cm each. Since a [[decimetre]] is 0.1 [[metre]]s then a '''decimetre cubed''' is 0.1 x 0.1 x 0.1 [[Metres Cubed|metres cubed]] (0.001m<sup>3</sup>).
: A '''decimetre cubed''' is the same [[Volume (Space)|volume]] as a [[litre]].
: [[Decimetres Cubed]] (dm<sup>3</sup>) are used in [[chemistry]] for the [[Volume (Space)|volume]] of [[gas]]es produced in [[Chemical Reaction|chemical reactions]].
: 1 [[mol]] of [[gas]] has a [[Volume (Space)|volume]] of 24dm<sup>3</sup> at [[STP|Standard Temperature and Pressure]].
