Measuring cups are kitchen tools used to measure the volume of ingredients, typically liquids or dry goods. They come in various sizes, usually marked in units such as cups, ounces, or milliliters. Common materials for measuring cups include plastic, glass, and stainless steel, each offering different advantages in terms of durability and ease of use. Most measuring cups have a spout for pouring and are designed to be easy to read, often featuring clear markings. Some sets include nested cups for convenient storage. Accurate measurements are essential in cooking and baking, as they ensure consistent results in recipes.
