About these units
Milliliter (mL)
A milliliter, defined as 1/1,000 of a liter or precisely 1 cubic centimeter, is a small but enormously significant volume unit in cooking, medicine, pharmacy, and laboratory science. Medical syringes, dosing spoons, and IV solutions rely heavily on milliliter accuracy. In laboratories, mL measurements are routine for preparing reagents, dilutions, and biological media. Because 1 mL = 1 cm³, many devices use either notation interchangeably depending on context. Despite its small size, the milliliter is commonly used in daily life as well—perfume bottles, beverage labels, and household cleaners often list contents in milliliters. Its precision and simplicity make the milliliter one of the world's most practical measurement 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.
