Which abbreviation indicates a measure of liquid volume in medicine?

The abbreviation that indicates a measure of liquid volume in medicine is "ml," which stands for milliliter. In medical contexts, milliliters are commonly used to measure volumes of liquids, such as medications or intravenous fluids. Understanding liquid measurements is crucial for accurate drug dosing, making milliliters an important unit for healthcare professionals, including medication aides.

The other abbreviations represent different types of measurements: "mg" stands for milligram, which measures weight, primarily for solid substances or the active components in medications. "cm" stands for centimeter, a unit of length and not relevant in the context of liquid volumes. "L," on the other hand, stands for liter, which is also a measure of liquid volume but is larger than a milliliter (1 liter equals 1000 milliliters). While "L" is indeed a measure of volume, "ml" is more commonly used for smaller liquid measurements in medication administration.
