To mL: multiply by 17.758. To US tablespoons: multiply by 1.201. To metric tablespoons: multiply by 1.184.
1 UK tbsp ≈ 17.758 mL = 3 UK tsp. About 20% larger than a US tablespoon (14.787 mL).
For example, 1 Tablespoon (UK) (tbsp (UK)) = 1.775820e+13 Femtoliter (fL).

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 femtoliter is a unit of volume equal to 10⁻¹⁵ liters, or one quadrillionth of a liter.
1 fL = 10⁻¹⁵ L = 10⁻¹² mL = 1,000 aL = 1 µm³ (cubic micrometer).
To liters: multiply by 10⁻¹⁵. To picoliters: divide by 1,000. To attoliters: multiply by 1,000.
Measuring red blood cell volumes (normal MCV: 80–100 fL), inkjet droplet sizes, and flow cytometry particle analysis.
A human red blood cell has a volume of about 90 fL. The smallest inkjet droplets are in the range of 1–5 fL.
Assuming fL is too small to be practical — it is actually the standard unit used on every complete blood count (CBC) lab report.
Remember: fL = femtoliter, the volume of blood cells. Normal MCV range: 80–100 fL. It's a key clinical measurement.
