About these units
Nanoliter (nL)
A nanoliter equals 10⁻⁹ liters and is commonly used in molecular biology, PCR (polymerase chain reaction), and analytical chemistry. Reaction volumes in high-throughput screening and micro-assays are frequently in nanoliters to conserve expensive reagents. In environmental science, trace samples of pollutants or micro-droplets in aerosols may be measured in nanoliters. Nanoliter volumes also arise in precision drug delivery systems and biomedical implants. The nanoliter represents a critical compromise between practical handling and microscopic precision, making it a cornerstone of modern microfluidic research.
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 Today, the US barrel appears in brewing, winemaking, certain agricultural commodities, and historical documents describing early American commerce.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.
