To mL: multiply by 11.839. To UK teaspoons: multiply by 2. To US dessertspoons: multiply by 1.201.
1 UK dsp ≈ 11.839 mL = 2 UK tsp ≈ 2/3 UK tbsp ≈ 0.417 UK fl oz.
For example, 1 Dessertspoon (UK) (dsp (UK)) = 1.183878e+13 Femtoliter (fL).

The UK dessertspoon is a unit of volume equal to approximately 11.839 milliliters, or 2 UK teaspoons.
1 UK dsp ≈ 11.839 mL = 2 UK tsp ≈ 2/3 UK tbsp ≈ 0.417 UK fl oz.
To mL: multiply by 11.839. To UK teaspoons: multiply by 2. To US dessertspoons: multiply by 1.201.
British and Indian recipes, traditional herbal medicine dosing, and Commonwealth cooking instructions.
The dessertspoon was originally designed for eating dessert — positioned between the teaspoon and tablespoon in a formal place setting.
Assuming all dessertspoons are the same size — UK (~12 mL), Australian (10 mL), and US (~10 mL) versions differ.
A UK dessertspoon ≈ 12 mL, roughly double a UK teaspoon. In modern cooking, use a 10 mL metric spoon as a close substitute.
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.
