The US tablespoon is a unit of culinary volume equal to 3 US teaspoons, or approximately 14.787 milliliters.
1 US tbsp = 3 US tsp = 1/2 US fl oz = 1/16 US cup ≈ 14.787 mL.
To mL: multiply by 14.787. To teaspoons (US): multiply by 3. To cups (US): divide by 16.
Measuring butter, oil, vinegar, and sauces in cooking. Common unit for salad dressing servings and medication doses.
A tablespoon of honey weighs about 21 grams, while a tablespoon of water weighs about 14.8 grams — density matters!
Confusing with the metric tablespoon (15 mL vs. 14.79 mL). Also, leveling vs. heaping tablespoons in baking.
2 tbsp = 1 fl oz (US). 16 tbsp = 1 cup. For quick metric conversion, 1 tbsp ≈ 15 mL (close enough for cooking).
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.
