Atomic Mass Unit

The unified atomic mass unit (u), also called the dalton (Da), is a unit of mass defined as one-twelfth of the mass of a carbon-12 atom at rest in its ground state, equal to approximately 1.66054 × 10⁻²⁷ kilograms. It is the standard unit used in chemistry and biochemistry for expressing atomic and molecular masses. The atomic mass unit facilitates comparison of the relative masses of atoms and molecules without requiring very small absolute numbers. 


Kilogram

The kilogram (also kilogramme) is the base unit of mass in the metric system, formally the International System of Units (SI), having the unit symbol kg. It is a widely used measure in science, engineering, and commerce worldwide, and is often simply called a kilo in everyday speech.
