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) = 3.519507973 Cup (UK) (cup (UK)).

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 UK (imperial) cup is a unit of volume equal to 10 UK fluid ounces, or approximately 284.131 milliliters.
1 UK cup = 10 UK fl oz = 1/2 UK pint = 284.131 mL ≈ 1.2 US cups.
To mL: multiply by 284.131. To US cups: multiply by 1.201. To liters: multiply by 0.284131.
Older British cookbooks, some Commonwealth recipes (especially pre-metric era), and traditional baking.
The UK cup is 20% larger than the US cup. A recipe calling for 1 UK cup actually requires about 1.2 US cups.
Using a US cup measure for a UK recipe — the 20% difference can ruin baked goods. Check the recipe's origin.
UK kitchens rarely use cups now — most British recipes specify grams and mL. If you see 'cups' in a UK recipe, it's 284 mL.
