because they are the same

Atomic Mass is the quantitive propertie of the mass of an atom,
the atomic mass unit is the (standard) UNIT by which it is measured:
1 a.m.u. = 1.66*10-27 kg
The atomic mass unit is not a SI unit. An atomic mass unit is equal to 1/12 from the atomic mass of the isotope 12C.
Atomic mass unit
The atomic mass unit is used to express the measure of the atomic mass.
AMU stands for atomic mass unit. 1 amu is 1.66053892 times 10 up to the negative 27 kilograms.
Atomic Mass Unit (amu)
Atomic mass is measured in a unit called an "atomic mass unit". This unit is defined as 1/12 of the mass of a carbon-12 atom at ground state.An atomic mass unit is approximately 1.66053886 x 10-27 kg.Atomic mass is measured in atomic mass units (amu) and Daltons.
the answer is the atomic mass unit
The atomic mass unit is 1/12 from the atomic mass of the isotope 12C.
The Atomic Mass unit is 1/12 from the atomic mass of the isotope carbon-12, in steady state.
The atomic mass unit is 1/12 from the atomic mass of the isotope carbon-12, in steady state.
Atomic mass is measured by atomic mass unit(amu) . It is given by 'u' i.e. unified mass.
expressed in unified atomic mass unit, amuHowever, for practical purposes in the laboratory the relative atomic mass is used so the unit would be gram. (Relative atomic mass compares the mass of all elements to that of the carbon-12 isotope taken as exactly 12)
