About these units
Barrel (Oil) (bbl (oil))
An oil barrel is defined as 42 US gallons, or 158.987 liters, and is a fundamental unit in the petroleum industry. This peculiar size traces back to the early Pennsylvania oil fields, where producers standardized whiskey barrels and modified wooden casks for oil transport. The need for consistent trade volumes cemented the 42-gallon barrel as the industry norm. Today, global oil production, pricing, and consumption are expressed in barrels—from daily OPEC reports to energy market forecasts. Even though oil is no longer physically shipped in barrels, the unit remains deeply embedded in international energy economics.
Cubic Centimeter (cm³)
A cubic centimeter equals 1 mL, representing the volume of a cube 1 cm per side. This dual identity makes it fundamental in medicine, laboratory science, and engineering. In medicine, cm³ is used when describing organ sizes, tumor volumes, or syringe capacities. In mechanics, engine displacements (e.g., "1500 cc") use cubic centimeters instead of liters, even though 1000 cm³ = 1 liter. The cm³ bridges small-scale measurements with scientific precision, making it indispensable across biology, chemistry, and automotive engineering.
