About these units
Liter (L, l)
The liter is one of the most widely used units of volume worldwide, defined as the volume of a cube measuring 10 centimeters on each side, making 1 L = 1,000 cubic centimeters = 1 cubic decimeter. Despite not being an SI base unit, it is fully accepted for use with the SI system due to its universal practicality. The liter occupies a sweet spot: large enough to measure beverages, fuel, and household liquids, yet small enough for precise laboratory use. Its intuitive scale simplifies everyday tasks—recipes, medical dosages, aquarium capacities, and fuel economy are all naturally expressed in liters. In science, the liter's alignment with the metric system makes it indispensable for expressing fluid volumes, solution concentrations (L in mol/L), and gas quantities under standard conditions. Industrial systems use liters for chemical processing, water treatment, and food production, making it a cornerstone of modern volume measurement.
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 Today, the US barrel appears in brewing, winemaking, certain agricultural commodities, and historical documents describing early American commerce.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.
