To liters: multiply by 10⁻¹⁵. To picoliters: divide by 1,000. To attoliters: multiply by 1,000.
1 fL = 10⁻¹⁵ L = 10⁻¹² mL = 1,000 aL = 1 µm³ (cubic micrometer).
For example, 1 Femtoliter (fL) = 6.762805e-14 Tablespoon (US) (tbsp (US)).

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.
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).
