About these units
Gill (US) (gi)
The US gill equals 118.294 mL, representing one-quarter of a US pint. Historically used in measuring alcoholic beverages, the gill once played a significant role in tavern regulations, distilling, and bartending. Its usage declined sharply after Prohibition and continued to fade as ounces and milliliters became preferred for drink recipes and consumer packaging. However, some old cocktail manuals still specify gills, and certain traditional American spirits were originally bottled in gill-based volumes. The gill illustrates the rich historical diversity of volumetric units in American culinary and beverage culture.
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.
