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.
A teaspoon (US) is a unit of volume measurement commonly used in American kitchens and food labeling. It is part of the US customary system and is typically abbreviated as "tsp." One US teaspoon is defined as exactly 4.92892 milliliters. It's also equivalent to one-third of a US tablespoon and one forty-eighth of a US cup.
This unit is frequently seen in recipes for small quantities of ingredients like salt, baking powder, or vanilla extract. It's also a common part of household measuring spoon sets, which usually include ¼, ½, and 1 teaspoon sizes.
Uses: The US teaspoon is widely used in both culinary and non-culinary contexts across the United States. The US teaspoon is a commonly used unit in everyday cooking, especially in baking, where accurate measurements of ingredients like spices, extracts, and baking powder are key to getting consistent results. Outside the kitchen, this small but essential unit is frequently used in healthcare as a standard measure for liquid medications, particularly when dosing for children. While medical professionals usually recommend milliliters for precision, many over-the-counter medicines in the US still refer to teaspoons as a practical reference.
