A milliliter (mL) is a unit of volume in the metric system, commonly used to measure liquids. One milliliter is equal to one-thousandth of a liter, which means that 1,000 milliliters make up one liter. This measurement is often used in cooking, medicine, and scientific experiments to ensure precise quantities. Milliliters are typically found on measuring tools like syringes, measuring cups, and graduated cylinders. They are essential for accurately dosing medications, mixing ingredients, and conducting experiments in laboratories. Understanding milliliters helps in various fields, including culinary arts, pharmacy, and chemistry.
