A milliliter (mL) is a small unit of measurement used to quantify liquid volume. It is part of the metric system, which is widely used around the world. One milliliter is equal to one-thousandth of a liter, making it a handy measurement for things like cooking, medicine, and science experiments. For example, a standard teaspoon holds about 5 milliliters of liquid. In everyday life, you might encounter milliliters when measuring ingredients for a recipe or dosing medicine. Many beverage containers, like water bottles or juice boxes, also list their volume in milliliters. Understanding milliliters helps you accurately measure liquids for various purposes, ensuring you get the right amount every time.
