What is the equivalent of one quart in cups according to U.S. measurements?

One quart is equivalent to four cups in U.S. measurements. This conversion is important to know, especially in various contexts such as cooking, baking, and nursing tasks that involve measuring fluids. The quart is a larger unit of measurement, and knowing that it contains four cups helps in accurately assessing liquid volumes. This relationship is based on the U.S. customary system, where a cup is one-fourth of a quart.
