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.
Gill (UK) (gi (UK))
A UK gill equals 142 mL, traditionally used in measuring spirits, whiskey, beer, and cooking ingredients. The gill was once a common pub measure, with quarter-gill and half-gill servings used before modern standardized alcohol units replaced them. While now mostly obsolete, the gill is still recognized in historical cocktail recipes, British literature, and the study of older trade practices.
