About Decimetres Cubed
- Decimetres Cubed are shortened to dm3 with with a lower case d and a lower case m.
- A decimetre cubed is the volume of a cube with sides of 10cm each. Since a decimetre is 0.1 metres then a decimetre cubed is 0.1 x 0.1 x 0.1 metres cubed (0.001m3).
- Decimetres Cubed (dm3) are used in chemistry for the volume of gases produced in chemical reactions.
- 1 mol of gas has a volume of 24dm3 at Standard Temperature and Pressure.
