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) = 1000 Attoliter (aL).

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 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.
