To mL: multiply by 9.858. To teaspoons (US): multiply by 2. To tablespoons (US): multiply by 0.667.
1 US dsp ≈ 2 US tsp ≈ 2/3 US tbsp ≈ 9.858 mL.
For example, 1 Dessertspoon (US) (dsp (US)) = 9.857843e+12 Femtoliter (fL).

The US dessertspoon is a unit of volume approximately double a teaspoon, equal to about 9.858 milliliters, or 2 US teaspoons.
1 US dsp ≈ 2 US tsp ≈ 2/3 US tbsp ≈ 9.858 mL.
To mL: multiply by 9.858. To teaspoons (US): multiply by 2. To tablespoons (US): multiply by 0.667.
Occasionally used in British/Australian recipes that have been adapted for US kitchens, and in traditional herbal medicine dosing.
The dessertspoon is a standard part of a formal European place setting, positioned between the soup spoon and teaspoon.
Confusing with a tablespoon — a dessertspoon is about 2/3 of a tablespoon, not half.
Think of the dessertspoon as 'double a teaspoon' — roughly 10 mL. It's the forgotten middle sibling of measuring spoons.
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.
