The abbreviation "kg" stands for kilogram, which is a unit of mass in the International System of Units (SI). The kilogram is defined as being equal to the mass of the International Prototype of the Kilogram, which is a platinum-iridium cylinder stored in France. This unit is widely used in various fields including science, industry, and healthcare to measure weight or mass, providing a standard when comparing measurements.

In contrast, a kilometer is a unit of length, not mass, and is commonly used to measure distances. A liter is a unit of volume used to quantify the space that a substance (usually a liquid) occupies. A gram is another unit of mass, which is one-thousandth of a kilogram, but it is not represented by the "kg" abbreviation. Thus, the choice of kilogram accurately reflects the measurement represented by "kg."
