About US tablespoon (tbsp)
The US tablespoon (tbsp) is a unit of culinary volume equal to approximately 14.787 milliliters, defined as 3 US teaspoons or half a US fluid ounce. It is a fundamental cooking measurement in the United States for both liquid and dry ingredients. Butter is measured in tablespoons (1 stick = 8 tbsp), as are cooking oils, sauces, and spices. The US tablespoon differs from the Australian tablespoon (20 mL) and the imperial tablespoon (17.76 mL).
One tablespoon of olive oil is about 14 g. A standard butter portion is 1 tbsp (≈ 14 g).
About Cubic decimeter (dm³)
A cubic decimeter (dm³) is the volume of a cube with sides of 10 centimeters, exactly equal to one liter (1 dm³ = 1 L). This equivalence is exact and defined by the SI. The cubic decimeter appears in physics and chemistry textbooks as the formal SI expression of volume where liters are used in practice, and in engineering calculations requiring dimensional consistency. One dm³ of pure water at 4°C has a mass of exactly one kilogram.
A standard 1-liter water bottle contains exactly 1 dm³. A typical lunchbox has a volume of roughly 2–3 dm³.
US tablespoon – Frequently Asked Questions
How many milliliters are in a US tablespoon?
One US tablespoon equals approximately 14.787 mL, typically rounded to 15 mL in culinary contexts. It equals 3 US teaspoons (3 × 4.929 mL = 14.787 mL).
How does the US tablespoon differ from the Australian tablespoon?
The Australian tablespoon is 20 mL — about 35% larger than the US tablespoon (14.79 mL). When using Australian recipes: 1 Australian tbsp ≈ 1.35 US tbsp. This is a significant difference in baking.
How many tablespoons are in a cup?
There are 16 US tablespoons in one US cup (240 mL): 1 cup = 16 tbsp = 48 tsp = 8 fl oz.
How much butter is in a tablespoon?
One US tablespoon of butter weighs approximately 14.2 grams (½ oz). A standard 4-oz US butter stick = 8 tablespoons = ½ cup.
Is a tablespoon the same in US and UK recipes?
No. A US tablespoon is about 14.79 mL; a UK/imperial tablespoon is about 17.76 mL — approximately 20% larger. Most modern UK recipes now use 15 mL metric tablespoons.
Cubic decimeter – Frequently Asked Questions
Is a cubic decimeter the same as a liter?
Yes, exactly. One cubic decimeter (dm³) is defined as equal to one liter (L). This is the foundational link between the cubic metric system and the liter-based system used in everyday measurement.
Why do textbooks use dm³ instead of liter?
In formal SI notation, volume is expressed in cubic meters or submultiples like dm³. The liter is accepted but technically non-SI. Chemistry texts use dm³ to maintain dimensional consistency, though liter and dm³ are completely interchangeable.
How many cubic decimeters are in a cubic meter?
There are 1,000 cubic decimeters in one cubic meter (m³), because 1 m = 10 dm and 10³ = 1,000. This also means 1 m³ = 1,000 liters.
What is the relationship between dm³ and cm³?
One cubic decimeter equals 1,000 cubic centimeters (cm³). Since 1 cm³ = 1 mL, it follows that 1 dm³ = 1 L = 1,000 mL — fully consistent within the metric system.
Where is the cubic decimeter used in practice?
The cubic decimeter appears primarily in scientific and educational contexts, particularly chemistry and physics where SI units are preferred. In everyday life, the liter is used instead — but they refer to the same volume.
