Which measurement corresponds to 'milligram'?

The measurement that corresponds to 'milligram' is represented by the abbreviation "mg." In the metric system, a milligram is one-thousandth of a gram and is commonly used in medicine to quantify small amounts of a substance, particularly in pharmaceuticals where dosing precision is crucial. The units of measurement mentioned in the other options serve different purposes; for instance, "ml" stands for milliliters, which is a measure of volume, particularly for liquids. "C" is not a standard measure in this context, and "ft" represents feet, a unit of length. Understanding these units and their appropriate contexts is essential in medical math, as accurate measurements can significantly impact patient care and treatment outcomes.
