The imperial tablespoon is a unit of volume once commonly used in the United Kingdom and countries that followed the imperial measurement system. One imperial tablespoon equals 17.7582 milliliters, making it noticeably larger than its US counterpart, which holds about 14.79 milliliters. It's abbreviated as tbsp and has long been a standard measure in British cooking and recipe instructions.
Although the UK now officially uses the metric system, the imperial tablespoon is still found in many traditional cookbooks and recipes. It belongs to the broader imperial set of volume measurements, including teaspoons, fluid ounces, and pints, and is often used in contexts where imperial units are still familiar and widely recognized.
Uses: The imperial tablespoon was once a staple in British kitchens, commonly used to measure liquids and dry ingredients such as flour, sugar, and syrups. It remains present in older recipes, especially those passed down through generations or found in vintage cookbooks that use imperial measures as the standard.
While modern kitchen tools in the UK tend to favor metric measurements, the imperial tablespoon is still referenced in some food packaging, serving sizes, and even pharmaceutical instructions. Understanding the imperial tablespoon is key to maintaining original proportions and flavor for cooks revisiting traditional British dishes or converting recipes accurately.
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.
