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.
Cup (UK) (cup (UK))
A UK cup equals 284 mL, slightly larger than both the US cup and the metric cup. Used historically in British cooking, the UK cup is now largely superseded by grams and milliliters, but it remains relevant when interpreting older recipe books and culinary traditions. Its intermediate size provided a convenient measure in a pre-metric world and still appears in baking communities that prefer imperial standards.
