The ratio of the average mass of the atom to the unified atomic mass unit. ... An atomic weight (relative atomic mass) of an element from a specified source is the ratio of the average mass per atom of the element to 1/12 of the mass of an atom of 12C. Atomic weight, also called relative atomic mass, is the ratio of the total weight of the atoms of a chemical substance to a norm. The normal unit of atomic mass has been one-twelfth of the atomic mass of the carbon-12 isotope since 1961.
