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) = 8.798770e-16 Quart (UK) (qt (UK)).

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 UK (imperial) quart is a unit of volume equal to 2 UK pints, or approximately 1,136.523 milliliters.
1 UK qt = 2 UK pt = 40 UK fl oz = 1/4 UK gallon ≈ 1,136.523 mL = 1.137 L.
To liters: multiply by 1.13652. To mL: multiply by 1,136.52. To US quarts: multiply by 1.201.
Older British recipes, some agricultural contexts, and historical trade measurements.
The UK quart (1,137 mL) is larger than a liter (1,000 mL), while the US quart (946 mL) is smaller than a liter.
Confusing UK and US quarts — they differ by about 20%. Always check which system a recipe or specification uses.
UK quart = 1.14 L (larger than a liter). US quart = 0.95 L (smaller than a liter). Easy way to remember the difference.
