Quart (US)
The US quart equals 2 pints or 32 fluid ounces (~946.353 milliliters). Its name derives from “quartus,” meaning one-fourth of a gallon. Quarts are used in cooking, beverage packaging, and household measures, providing a convenient medium-sized unit. The quart’s integration into the US customary system allows cooks and manufacturers to scale recipes and liquid volumes efficiently.
Teaspoon (Metric)
The metric teaspoon equals 5 milliliters, standardized to simplify cooking and medical measurements in countries that use the metric system. Unlike the US teaspoon, the metric teaspoon is slightly larger (5 mL vs ~4.92892 mL) and is widely used in recipes, pharmaceutical dosing, and nutrition labeling. Its simplicity ensures consistency across recipes and instructions internationally.
