About these units
Centigram (cg)
A centigram, equal to 1/100 of a gram, is an intermediate unit not frequently encountered in everyday life but occasionally useful in laboratory settings and chemical formulations. Its size offers a compromise between the larger gram and the smaller milligram, especially in contexts like dietetics, powdered chemicals, or small-scale industrial ingredients. Though not widely used, the centigram's value lies in its flexibility—providing a metric option for moderate precision without resorting to decimals.
Kilogram (kg)
The kilogram is the base unit of mass in the SI system and the only SI unit defined directly by a fundamental constant rather than a physical object. Originally, its definition was tied to a platinum–iridium artifact stored in France—the famous "International Prototype Kilogram." Over time, tiny mass changes in the prototype and its official copies created difficulties for high-precision science. In 2019, the kilogram was redefined using Planck's constant, linking mass to the laws of quantum physics through the Kibble balance. This innovation ensures universality, stability, and reproducibility across the world. The kilogram is central to commerce, science, engineering, and every quantitative field dealing with matter. Its decimal relationships with other metric units (grams, milligrams, tons) make it universally convenient. From groceries to spacecraft mass budgets, the kilogram anchors modern mass measurement.
