The quart (US) is a unit of liquid volume in the U.S. customary system, equal to 32 US fluid ounces or approximately 946.353 milliliters. It's abbreviated as qt and is defined as one-fourth of a US gallon. A quart is also twice the size of a US pint and one-eighth of a gallon, making it a convenient middle-range measurement for recipes, packaging, and household use.
In American kitchens, the quart is commonly used for liquids like milk, broth, juice, and cooking oils. It's a standard size for measuring cups and storage containers and is widely seen in both home cooking and grocery products.
Uses: The US quart is frequently used in recipes that call for larger volumes of liquid soups, stews, stocks, and marinades. It's also a common reference point for batch cooking and food storage. Many kitchen containers and measuring pitchers are marked in quarts, making it easy for home cooks to portion ingredients accurately.
Outside the kitchen, quarts are used in food and beverage packaging, such as milk cartons, ice cream tubs, and juice bottles. The unit also appears in automotive contexts, where motor oil is sold in quarts. Thanks to its versatility and widespread recognition, the quart continues to be a trusted unit in both culinary and everyday settings.
The imperial quart is a unit of volume from the imperial system, primarily used in the United Kingdom and some Commonwealth countries. One imperial quart equals 1.13652 liters or 40 imperial fluid ounces, making it larger than the US quart, which holds about 946 milliliters. It's abbreviated as qt and traditionally used to measure liquids and dry goods in household and commercial settings.
In the imperial system, a quart is equal to one-fourth of a gallon and twice the volume of a pint. Though metric units have largely replaced imperial measures in the UK, the quart still appears in older recipes, cooking references, and some product labels—especially in contexts where traditional measurements remain familiar and practical.
Uses: The imperial quart is often seen in vintage British recipes, where it's used to measure liquids like broth, milk, or cream. It also shows up in older cookbooks, measuring jugs, and kitchenware that still use imperial markings. While not as common in everyday packaging today, you might still encounter quarts in contexts like traditional food preparation or when referencing older British standards.
