Atomic Mass Unit
An atomic mass unit is defined as one twelfth of the mass of a carbon-12 atom.
History: It was standardized to make atomic and molecular masses easier to compare.
Current use: Atomic mass units are used in chemistry, physics, and molecular science.
Also written as u, amu, dalton, daltons, Da.
Kilogram
A kilogram equals 1,000 grams and is the SI base unit of mass.
History: Its definition is now tied to the Planck constant rather than a physical artifact.
Current use: Kilograms are standard for body weight, shipping, and commerce.
Also written as kg, kilograms, kgs, kilo, kilos.
