SUMMARY
The terms "amu" (atomic mass unit) and "u" (unified atomic mass unit) refer to the same measurement of mass in atomic physics, with both representing 1/12 the mass of a carbon-12 atom. The symbol "Da" (Dalton) is also used interchangeably with these units, particularly in the context of molecular mass. While "u" is often preferred in scientific literature, both terms are accepted and understood in chemistry and related fields. Understanding these units is crucial for accurate calculations in atomic and molecular mass.
