To liters: 1 dm³ = 1 L (exact). To cubic meters: divide by 1,000. To gallons (US): multiply by 0.264172.
1 dm³ = 0.001 m³ = 1 L = 1,000 cm³ = 10⁶ mm³. One cubic meter contains 1,000 dm³.
For example, 1 Cubic Decimeter (dm³) = 0.00628981077 Barrel (US) (bbl (US)).

The cubic decimeter is a unit of volume equal to a cube with edges of one decimeter (0.001 m³), and is exactly equal to one liter.
1 dm³ = 0.001 m³ = 1 L = 1,000 cm³ = 10⁶ mm³. One cubic meter contains 1,000 dm³.
To liters: 1 dm³ = 1 L (exact). To cubic meters: divide by 1,000. To gallons (US): multiply by 0.264172.
Used interchangeably with liters — applicable to beverage volumes, fuel measurements, and container sizing.
The dm³ is one of the few SI-derived units that has a more popular non-SI alternative (the liter) used even in scientific contexts.
Not recognizing that 1 dm³ = 1 L exactly. Some assume they are only approximately equal due to historical definitions.
Visualize a cube that is 10 cm × 10 cm × 10 cm — that is one dm³ and also exactly one liter.
The US barrel is a unit of volume equal to 31.5 US gallons (about 119.24 liters), used for various liquid commodities.
1 US barrel = 31.5 US gal = 119.24 L = 0.11924 m³ = 4,032 US fl oz.
To liters: multiply by 119.24. To US gallons: multiply by 31.5. To UK barrels: multiply by 0.729.
Brewery production volumes, whiskey barrel aging, wine production, and bulk liquid commodity trading.
A bourbon whiskey barrel is 53 gallons (200 L), larger than the standard US liquid barrel. Barrel sizes vary by commodity and country.
Confusing the US liquid barrel (31.5 gal) with the petroleum barrel (42 gal). Always specify which barrel type.
There are several different 'barrel' sizes. US liquid = 31.5 gal, US oil = 42 gal, UK = 36 imperial gal. Always specify!
