About these units
Atomic Mass Unit (u)
The atomic mass unit (u) is defined as exactly 1/12 the mass of a neutral carbon-12 atom, which makes it approximately 1.66053906660 × 10⁻²⁷ kilograms. This definition allows scientists to express atomic and molecular masses in a convenient, intuitive scale that aligns with the structure of the periodic table. By anchoring the unit to carbon-12, chemists and physicists gained a universal reference point that harmonizes molecular weight, relative isotopic abundance, and mass spectroscopy results. The atomic mass unit effectively normalizes the complexity of atomic masses into whole-number or near-whole-number values for most nuclei. In chemistry, u is indispensable for calculating molar masses, reaction stoichiometry, and isotopic compositions. It is also used across nuclear physics, astrophysics, and biophysics, demonstrating the universality of atomic-scale measurement.
Dekagram (dag)
A dekagram, equal to 10 grams, is used more commonly in parts of Europe, particularly in culinary contexts such as baking or meat sales. Its size is practical for recipes, nutrition labeling, and small food packages. It avoids large numbers in grams without jumping to the heftier hectogram or kilogram. While less familiar in English-speaking countries, the dekagram is valued in regions where metric cooking traditions are strong.
