What unit is abbreviated as "mg." in the context of weight measurement?

The abbreviation "mg" stands for milligram, which is a unit of mass in the metric system. A milligram is one-thousandth of a gram, making it a commonly used measurement, especially in healthcare, for dosages of medications and supplements. Understanding this unit is crucial for accurate medication administration, as many pharmaceuticals require precise dosing.

The other units mentioned have different meanings and contexts. A microgram, abbreviated as "μg," is one-millionth of a gram, which is smaller than a milligram. A megagram, or "Mg," is equivalent to one thousand grams, which is much larger than a milligram. Lastly, a milliliter, abbreviated as "mL," measures volume rather than weight, which is a different context altogether. Therefore, in a weight measurement context, "mg" specifically refers to milligrams.
