How many milliliters are there in one liter?

One liter is equivalent to 1000 milliliters. This is based on the metric system's definition of volume, where 1 liter is universally standardized to equal 1000 milliliters. Understanding this relationship is essential in nursing and medical settings, where precise measurements of liquids are often required for medications, intravenous fluids, and other clinical applications. Knowing that 1000 milliliters make up a liter can help professionals accurately convert and administer fluid volumes as needed.
