To liters: multiply by 10¹⁵. To km³: multiply by 1,000. To teraliters: multiply by 1,000.
1 PL = 10¹⁵ L = 10¹² m³ = 1,000 km³ = 1,000 TL. One exaliter = 1,000 PL.
For example, 1 Petaliter (PL) = 1.000000e+30 Femtoliter (fL).

The petaliter is a unit of volume equal to 10¹⁵ liters, or 1,000 cubic kilometers.
1 PL = 10¹⁵ L = 10¹² m³ = 1,000 km³ = 1,000 TL. One exaliter = 1,000 PL.
To liters: multiply by 10¹⁵. To km³: multiply by 1,000. To teraliters: multiply by 1,000.
No everyday practical use. Used for expressing very large natural water volumes in scientific literature.
All the world's rivers contain approximately 2.12 PL of water. Earth's ice caps hold about 26.5 PL of freshwater.
Rarely encountered, so the main mistake is not understanding the scale: 1 PL = one quadrillion liters.
Petaliters describe planet-scale volumes. Earth's total freshwater ≈ 35 PL. The prefix chain: kilo, mega, giga, tera, peta.
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.
