About these units
Attoliter (aL)
An attoliter is a staggering 10⁻¹⁸ liters, placing it firmly in the realm of molecular and nanoscale science. This unimaginably small volume corresponds to spaces comparable to the inside of viruses, nanopores, or clusters of biomolecules. Cutting-edge technologies like nano-droplet reactors, atomic force microscopy, and high-precision spectroscopy rely on attoliters to describe reaction chambers or sample sizes. The attoliter is so small that even a single bacterial cell has a volume approximately one million attoliters. This makes the unit essential for exploring the physical limits of chemical reactions and biological processes.
Barrel (US) (bbl (US))
The US barrel is a unit with multiple definitions depending on the industry, though the most common general-purpose US barrel is 31.5 US gallons, used historically for dry goods, ale, and various agricultural products. In practice, the US barrel arose from traditional cask-making, where wooden barrels of different shapes were used for storage and transport. Because their capacity varied widely, different industries standardized the barrel at different volumes. Over time, manufacturers and commercial sectors adopted specific barrel sizes for consistency. Today, the US barrel appears in brewing, winemaking, certain agricultural commodities, and historical documents describing early American commerce. Its varied legacy makes it a fascinating example of an evolving unit shaped by economic necessity and craftsmanship.
