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.
A milliliter is a metric unit of volume used around the world for measuring small amounts of liquid. It's abbreviated as mL and is defined as one-thousandth of a liter—making it ideal for precise, everyday measurements. One milliliter is equal to 1 cubic centimeter (cm³) and roughly 0.034 fluid ounces (US).
Because of its precision and simplicity, the milliliter is a standard in science, medicine, cooking, and packaging. Whether you're reading a nutrition label, following a recipe, or measuring out a medication dose, the milliliter is a practical and widely accepted unit in both personal and professional settings.
Uses: The milliliter is used globally in a wide range of applications. In the kitchen, it helps measure small liquid quantities like vanilla extract, lemon juice, or oil. On food packaging, beverages, and household products, you'll often see volumes listed in milliliters to indicate serving sizes or total content.
In healthcare, the milliliter is critical for accurately dosing liquid medications, especially in syringes and measuring cups. The milliliter is often seen in labs and industries where accurate volume is expected. It’s also used on packaging, recipe cards, and medicine labels to keep measurements clear and consistent in everyday use.
