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 cup (US) is a standard unit of volume used in American cooking and baking. It's part of the U.S. customary system and is commonly abbreviated as cup or sometimes c in recipes. One US cup equals exactly 236.588 milliliters, and it's defined as 1/16 of a US gallon or 8 US fluid ounces.
In American kitchens, a cup is one of the foundational units in recipe measurement. It's used for both dry and liquid ingredients, making it a flexible and practical choice for home cooks. Measuring cups—available in sets ranging from ¼ cup to 1 cup—are essential tools in households across the country.
Uses: The US cup is widely used in recipes for measuring ingredients like flour, sugar, milk, oil, and grains. It provides a simple and consistent way to portion both dry and wet ingredients, which is especially important in baking where ratios must be precise.
You'll also find the cup used in nutrition guides and food labels, particularly when describing serving sizes. In everyday cooking, it's a go-to unit that makes scaling recipes up or down much easier. Whether you're following a recipe from a cookbook, a food blog, or a product package, the US cup is likely to be one of the most frequently referenced measurements.
