The imperial cup is a unit of volume that was historically used in the United Kingdom and other countries that followed the imperial measurement system. One imperial cup is equal to 284.131 milliliters, making it slightly larger than the US cup, which holds about 236.588 milliliters. While not as widely used today due to the UK's adoption of the metric system, the imperial cup still appears in older recipes, cookbooks, and household measurements.
It was designed to be a convenient mid-range measure—larger than a tablespoon but smaller than a pint. In many traditional British kitchens, the cup was used for dry and liquid ingredients, often measured with simple household items or standard measuring cups that followed imperial standards.
Uses: The imperial cup is most commonly seen in classic British recipes and cookbooks written before metrication. It measured ingredients like flour, sugar, milk, and oil in home and professional kitchens. Even today, you may find imperial cup references in family recipes passed down over generations or in online conversions of older dishes.
Though the UK now uses grams and milliliters for most cooking and product packaging, the imperial cup still holds relevance for those recreating traditional British meals or converting recipes that rely on imperial units. It also occasionally appears on measuring cups that include metric and imperial markings, helping home cooks bridge the gap between old and new systems.
The imperial fluid ounce is a unit of volume from the imperial measurement system, traditionally used in the United Kingdom and other Commonwealth countries. One imperial fluid ounce is equal to 28.4131 milliliters, which makes it slightly larger than the US fluid ounce (approximately 29.57 mL in the US system). It's commonly abbreviated as fl oz and was widely used for measuring liquids in recipes, packaging, and day-to-day household tasks.
Uses: The imperial fluid ounce was once a standard unit in British kitchens, used to measure ingredients such as milk, oil, and other cooking liquids. While most modern recipes in the UK now use milliliters or grams, many older or traditional recipes still list quantities in fluid ounces. This makes the unit especially relevant for those cooking from classic British cookbooks or following long-standing family recipes.
The imperial fluid ounce still appears on many UK labels, especially for drinks, personal care products, and older medicinal packaging. Whether you're following a traditional recipe or measuring from labeled packaging, knowing how this unit works helps you convert accurately and maintain consistency.
