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+15 Attoliter (aL).

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 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.
