The UK tablespoon is a unit of culinary volume equal to approximately 17.758 milliliters, or 3 UK teaspoons.
1 UK tbsp ≈ 17.758 mL = 3 UK tsp. About 20% larger than a US tablespoon (14.787 mL).
To mL: multiply by 17.758. To US tablespoons: multiply by 1.201. To metric tablespoons: multiply by 1.184.
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 attoliter is an extremely small unit of volume equal to 10⁻¹⁸ liters, or one quintillionth of a liter.
1 aL = 10⁻¹⁸ L = 10⁻²¹ m³ = 10⁻¹⁵ µL. One femtoliter = 1,000 aL.
To liters: multiply by 10⁻¹⁸. To femtoliters: divide by 1,000. To cubic nanometers: 1 aL = 10⁶ nm³.
Measuring individual molecular reaction volumes, nano-droplet volumes, and single-cell compartments.
A typical virus capsid can enclose a volume of just a few attoliters. The interior of a ribosome is measured in attoliters.
Confusing attoliters with femtoliters — there are 1,000 aL in 1 fL. The scale difference is enormous.
Prefix ladder: milli → micro → nano → pico → femto → atto. Each step is 10⁻³ smaller than the last.
