About these units
Cup (US) (cup (US))
A US cup equals 8 fluid ounces, or approximately 236.588 mL. It is indispensable in American cooking, baking, and beverage measurement. Although not an SI unit, the cup remains deeply entrenched in recipes, cookbooks, and kitchen culture. Its intuitive size makes it ideal for measuring flour, sugar, liquids, and many everyday ingredients. American cups differ from metric and UK cups, leading to variation across international recipes, but within the US culinary tradition, the cup is a central volumetric tool.
Gallon (UK) (gal (UK))
The UK gallon, defined as 4.54609 liters, is larger than the US gallon by nearly 20%. It originated from the British desire to standardize wine and ale measures, leading to a uniform definition during the 19th century. Today, the UK gallon appears in older recipes, fuel consumption discussions, and British Commonwealth trade documents. Although the UK now uses liters for petrol and milk, the gallon remains culturally familiar, especially in automotive contexts such as miles per gallon (MPG), where both imperial and US definitions cause frequent confusion. The UK gallon's legacy persists through its continued use in some Commonwealth nations and specialized industries where imperial measures remain customary.
