Which unit of measurement corresponds to kilogram?

The unit of measurement that corresponds to kilogram is kg. A kilogram is a standard unit in the metric system and is commonly used to measure mass. It is defined as being equal to 1,000 grams (g). Therefore, the abbreviation "kg" stands for kilogram and is universally recognized in scientific and medical contexts.

The other options represent different units of mass or weight: grams (g) is a smaller unit than kilograms, pounds (lb) is a unit used primarily in the Imperial system, and micrograms (mcg) is an even smaller unit, where 1 kilogram equals 1,000,000 micrograms. These distinctions in measurement units are important to understand, especially when calculating dosages in medication administration.
