Liquid measuring cups are kitchen tools designed to accurately measure liquid ingredients like water, milk, and oil. They typically have a spout for easy pouring and are marked with measurement lines in both metric and imperial units. Common materials include glass, plastic, and stainless steel, each offering different benefits such as durability and ease of cleaning. These cups come in various sizes, often ranging from 1 cup to 8 cups or more. Some models feature a handle for better grip, while others may have measurement markings on the side for quick reference. Using a liquid measuring cup ensures precise ingredient amounts, which is essential for successful cooking and baking.
