The imperial teaspoon is a unit of volume used primarily in the United Kingdom and other countries that once followed the imperial measurement system. It's slightly smaller than the US teaspoon, with one imperial teaspoon equal to 4.7355 milliliters. This unit is abbreviated as tsp and has historically appeared in older British cookbooks and kitchenware.
While the imperial system has been largely replaced by the metric system in the UK, many traditional recipes and household items still reference the imperial teaspoon. It's part of a broader set of imperial volume measurements, including tablespoons, fluid ounces, and pints.
Uses: The imperial teaspoon was once a standard unit in British kitchens, used to measure ingredients like sugar, baking powder, and liquid extracts. Though the UK officially uses the metric system today, imperial units still appear in everyday cooking, particularly in family recipes passed down through generations.
You may also see the imperial teaspoon referenced in medication dosages or on packaging in regions that retain imperial labeling. While modern measuring tools often default to metric or US volumes, the imperial teaspoon remains relevant for those following traditional British cooking or converting older recipes accurately.
The imperial quart is a unit of volume from the imperial system, primarily used in the United Kingdom and some Commonwealth countries. One imperial quart equals 1.13652 liters or 40 imperial fluid ounces, making it larger than the US quart, which holds about 946 milliliters. It's abbreviated as qt and traditionally used to measure liquids and dry goods in household and commercial settings.
In the imperial system, a quart is equal to one-fourth of a gallon and twice the volume of a pint. Though metric units have largely replaced imperial measures in the UK, the quart still appears in older recipes, cooking references, and some product labels—especially in contexts where traditional measurements remain familiar and practical.
Uses: The imperial quart is often seen in vintage British recipes, where it's used to measure liquids like broth, milk, or cream. It also shows up in older cookbooks, measuring jugs, and kitchenware that still use imperial markings. While not as common in everyday packaging today, you might still encounter quarts in contexts like traditional food preparation or when referencing older British standards.
