How many mL are in 1 liter?

One liter is equivalent to 1000 milliliters. This relationship is based on the metric system, where the prefix 'milli-' denotes one-thousandth of a unit. Therefore, when converting liters to milliliters, you multiply by 1000. Since a liter is a standard unit of volume in the metric system, this conversion is fundamental and widely used in healthcare and scientific contexts. Understanding this conversion is essential for accurate medication dosing and fluid management in medical practice. Other values listed do not represent the correct metric conversion for liters to milliliters, as they do not correspond to the standard measurement.
