Traditional British baking and cooking, Commonwealth recipes, and older pharmaceutical references.
Australia officially uses a 20 mL tablespoon, the UK uses ~17.8 mL, and the US uses ~14.8 mL — three different sizes for the same name!
Mixing up UK and US tablespoons in international recipes. A UK tbsp is ~20% larger than a US tbsp.
Modern UK cooking is shifting to metric (15 mL). When following old UK recipes, add ~20% more than a US tbsp would indicate.
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.
