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.
The tablespoon (US) is a unit of volume used in the US customary system. It's commonly abbreviated as tbsp, T, or tbs, and it plays a central role in measuring both liquid and dry ingredients in American recipes. By definition, one US tablespoon equals 14.7868 milliliters, making it exactly three times the size of a US teaspoon.
This unit is a standard part of measuring spoon sets found in nearly every American kitchen. It's used for ingredients that require more than a teaspoon but less than a full cup—like oil, syrup, peanut butter, or baking powder. Whether you're preparing a sauce, salad dressing, or baked goods, the tablespoon offers an ideal balance between precision and practicality.
Uses: The tablespoon is one of the most commonly used measurements in American kitchens. You’ll find it in countless recipes—from marinades and sauces to pancake batter and salad dressings. In baking, it plays a critical role, where just a small difference in the amount of butter, oil, or leavening agent can change the texture or taste of the final dish. The tablespoon is also used in meal prep, portion control, and nutritional labeling, helping consumers track ingredients like sugar, oils, or dressings in a standardized way.
Beyond the kitchen, the U.S. tablespoon occasionally appears in medical or pharmaceutical contexts to measure over-the-counter liquid medications, though healthcare professionals typically recommend using milliliters for precision. Still, the tablespoon remains a familiar and convenient reference point for many households.
