atomic mass unit
An atomic mass unit, often abbreviated as amu, is a unit of mass that is approximately equal to the mass of a proton or neutron. It is defined as 1/12th the mass of an unbound neutral atom of carbon-12 in its ground state. The atomic mass unit is used primarily in atomic physics, chemistry, and biochemistry to express the masses of atoms, molecules, and chemical compounds.

Atomic mass unit
The unified atomic mass unit or dalton is the standard unit that is used for indicating mass on an atomic or molecular scale. One unified atomic mass unit is approximately the mass of a nucleon and is equivalent to 1 g/mol. It is defined as one twelfth of the mass of an unbound neutral atom of carbon-12 in its nuclear and electronic ground state, and has a value of 1.660538921×10^−27 kg. The CIPM has categorised it as a non-SI unit accepted for use with the SI, and whose value in SI units must be obtained experimentally. The amu without the "unified" prefix is technically an obsolete unit based on oxygen, which was replaced in 1961. However, some sources still use the amu but now define it in the same way as u. In this sense, most uses of atomic mass units or amu today actually refer to unified atomic mass units or u. Atomic mass unit does not stand for the unit of mass in the atomic units system, which is rather me.
