Definition
- Noun:
- A metric unit of volume: A cubic decimetre is a unit of volume in the metric system, defined as the volume of a cube with sides each one decimetre (10 centimetres) in length. It is exactly equal to 1,000 cubic centimetres (cm³) or one litre (L). Historically, it was defined as the volume occupied by one kilogram of pure water at its maximum density and under standard atmospheric pressure.
Examples of Usage
- Noun:
- The engine has a displacement of two cubic decimetres.
- One cubic decimetre of water has a mass of approximately one kilogram.
- The recipe requires 1.5 cubic decimetres of milk.
Advanced Usage
- Scientific and Technical Context: The term "cubic decimetre" (dm³) is often used interchangeably with the litre (L) in scientific measurements, though the litre is the more common unit for everyday capacity. In precise scientific work, the cubic decimetre is the coherent SI unit for volume.
- The density of the substance is 2.7 grams per cubic decimetre.

- Litre (Liter): A unit of volume equal to one cubic decimetre.
- Decimetre (Decimeter): A unit of length equal to one-tenth of a metre, the fundamental unit for the cubic decimetre.
Synonyms

- Cubic centimetre (cm³ or cc): A smaller metric unit of volume; 1,000 cubic centimetres equal one cubic decimetre.
Noun
- a metric unit of capacity, formerly defined as the volume of one kilogram of pure water under standard conditions; now equal to 1,000 cubic centimeters (or approximately 1.75 pints)
