What is a Cup (US) and a Quart?
The US customary cup is a unit of volume used in the United States for cooking and serving sizes. It is defined as exactly 8 US customary fluid ounces. This equates to approximately 236.59 milliliters (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.

History of the Cup (US) and Quart
The concept of a 'cup' as a measurement unit evolved informally over centuries. The US customary cup was standardized based on the US gallon, which itself derived from the older English wine gallon. Unlike the metric cup (250 mL) or the imperial cup (approx. 284 mL), the US cup was legally defined in terms of the gallon (1 US gallon = 16 US cups).
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.
