About these units
Gallon (US) (gal (US))
The US gallon is defined as exactly 231 cubic inches, or 3.785411784 liters. It is widely used in American commerce for gasoline, milk, water, and other household liquids. Its historical roots lie in old English wine and ale gallons, whose varying definitions ultimately led to divergent US and UK systems. Today, the US gallon remains deeply embedded in American culture, especially in automotive contexts—fuel economy ratings such as "miles per gallon" (MPG) illustrate its everyday relevance. Despite the global shift toward metric volume units, the US gallon persists due to familiarity and regulatory inertia. It remains an iconic unit, symbolizing uniquely American measurement traditions.
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.
