The cup (US) is a standard unit of volume used in American cooking and baking. It's part of the U.S. customary system and is commonly abbreviated as cup or sometimes c in recipes. One US cup equals exactly 236.588 milliliters, and it's defined as 1/16 of a US gallon or 8 US fluid ounces.
In American kitchens, a cup is one of the foundational units in recipe measurement. It's used for both dry and liquid ingredients, making it a flexible and practical choice for home cooks. Measuring cups—available in sets ranging from ¼ cup to 1 cup—are essential tools in households across the country.
Uses: The US cup is widely used in recipes for measuring ingredients like flour, sugar, milk, oil, and grains. It provides a simple and consistent way to portion both dry and wet ingredients, which is especially important in baking where ratios must be precise.
You'll also find the cup used in nutrition guides and food labels, particularly when describing serving sizes. In everyday cooking, it's a go-to unit that makes scaling recipes up or down much easier. Whether you're following a recipe from a cookbook, a food blog, or a product package, the US cup is likely to be one of the most frequently referenced measurements.
The imperial gallon is a unit of volume used in the imperial measurement system, and it is historically common in the United Kingdom and several other countries. One imperial gallon is equal to 4.54609 liters, which makes it significantly larger than the US gallon (approximately 3.785 liters). It is abbreviated as gal and traditionally used for measuring liquids in larger quantities.
In the imperial system, a gallon is made up of four quarts, eight pints, or 160 imperial fluid ounces. Though the UK has officially adopted the metric system, the imperial gallon is still recognized in specific contexts and remains part of British measurement history. It's most commonly associated with fuel pricing and older food or drink packaging.
Uses: The imperial gallon is most commonly seen today at fuel stations in the UK, where petrol and diesel are still sold by the gallon for pricing comparisons, even though the actual quantity delivered is measured in liters. Historically, the gallon was used for everything from milk deliveries to beer and cider sales.
While modern recipes and packaging have largely shifted to liters and milliliters, the imperial gallon occasionally appears in traditional instructions or product specs, especially for bulk liquids. For those referencing older materials or converting classic measurements, the imperial gallon remains a useful and historically significant unit.
