How to Convert Femtoliter to Cup (US)
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) = 4.226753e-15 Cup (US) (cup (US)).

About Femtoliter (fL)
Definition
The femtoliter is a unit of volume equal to 10⁻¹⁵ liters, or one quadrillionth of a liter.
Mathematical Relationship
1 fL = 10⁻¹⁵ L = 10⁻¹² mL = 1,000 aL = 1 µm³ (cubic micrometer).
Conversion Formula
To liters: multiply by 10⁻¹⁵. To picoliters: divide by 1,000. To attoliters: multiply by 1,000.
Practical Applications
Measuring red blood cell volumes (normal MCV: 80–100 fL), inkjet droplet sizes, and flow cytometry particle analysis.
Interesting Facts
A human red blood cell has a volume of about 90 fL. The smallest inkjet droplets are in the range of 1–5 fL.
Common Mistakes
Assuming fL is too small to be practical — it is actually the standard unit used on every complete blood count (CBC) lab report.
Educational Tips
Remember: fL = femtoliter, the volume of blood cells. Normal MCV range: 80–100 fL. It's a key clinical measurement.
About Cup (US) (cup (US))
Definition
The US cup is a unit of culinary volume equal to 8 US fluid ounces, or approximately 236.588 milliliters.
Mathematical Relationship
1 US cup = 8 US fl oz = 16 US tbsp = 48 US tsp = 1/2 US pint ≈ 236.588 mL.
Conversion Formula
To mL: multiply by 236.588. To liters: multiply by 0.236588. To UK cups: multiply by 0.832674.
Practical Applications
Measuring flour, sugar, milk, water, and other cooking ingredients. Standard in every American cookbok and food label.
Interesting Facts
The US cup, metric cup (250 mL), and Japanese cup (200 mL) are all different sizes — international recipes can be confusing!
Common Mistakes
Using a coffee mug as a 'cup' — mugs range from 200–350 mL. Always use a calibrated measuring cup for accuracy.
Educational Tips
Key conversions: 1 cup = 16 tbsp = 8 fl oz = 1/2 pint. For metric: 1 cup ≈ 240 mL (close enough for cooking).
