About these units
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.
Decigram (dg)
A decigram equals 1/10 of a gram and appears in older scientific literature, pharmaceutical compounding, and some food chemistry applications. Today, milligrams and grams are more common, but decigrams still offer practical value when describing masses that naturally fall between these scales, such as certain supplements or cosmetic ingredients. The decigram remains a reminder of the metric system's logical progression, offering users a consistent, scalable set of units.
