What is a Cup and a Quart?
The cup is a unit of volume used in cooking and measurements. The most common definition is the US customary cup (approx. 236.59 ml), but other definitions exist (e.g., metric cup = 250 ml).
The US liquid quart (symbol qt US) is a unit of volume in the United States customary units system. It is equal to one-quarter of a US gallon, which is exactly 57.75 cubic inches or approximately 0.946 liters. It is commonly used for measuring medium quantities of liquids, such as milk, oil, and juices.
Note: The Cup is part of the imperial/US customary system, primarily used in the US, UK, and Canada for everyday measurements. The Quart belongs to the imperial/US customary system.
History of the Cup and Quart
The cup evolved as a traditional, informal unit of measurement in cooking, often related to the size of a typical teacup.
The quart, meaning 'quarter part' (of a gallon), shares its history with the gallon. The US liquid quart is derived from the English wine gallon (231 cubic inches), making it distinct from the Imperial quart used elsewhere, which is based on the larger Imperial gallon.

Frequently Asked Questions
Questions About Cup (cup)
Is a cup the same everywhere?
No, the volume of a "cup" can vary significantly by region (e.g., US customary ≈ 237 mL, US legal = 240 mL, metric = 250 mL, imperial ≈ 284 mL). This converter primarily uses the US customary cup unless otherwise specified in the context of a specific conversion pair.
How many tablespoons are in a cup?
In the US customary system, there are 16 tablespoons in 1 cup. This is a useful conversion to remember for scaling recipes up or down, especially when working with smaller quantities.
Is a dry cup different from a liquid cup?
Yes, in the US customary system, there is a distinction between dry and liquid cup measurements. While they have the same volume (8 fluid ounces), they are measured differently. Liquid cups are typically measured to the brim in a liquid measuring cup, while dry cups are measured by filling and leveling off in a dry measuring cup. For precise cooking results, it's best to use the appropriate measuring tool for each type of ingredient.
