No, the SI unit of mass is still the kilogram. However, the AMU has been accepted as a suitable standard unit.
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.
The SI unit for mass is the kilogram - whether for an atomic particle of for a galaxy.
The SI unit is the unified atomic mass unit (amu), the symbol is u. Or Dalton, the symbol is Da.
The Si unit used for the masses of particles is the atomic mass unit (amu).
AMU (Atomic Mass Unit) is the SI masses of particles for nucleus.
Atomic mass is a mass, the SI units of mass are kg. The atomic mass unit is equal to one-twelfth the mass of a carbon-12 atom or 1,660538921(73)×10−27 kg. Atomic mass unit is recognized now as a non-SI unit.
1 atomic mass unit is equivalent to the 1/12 the mass of a carbon-12 atom at rest. This is not considered an si unit because it is defined by a definition and not experimentally
The SI unit for mass is kilogram. Mass is not a unit.
si unit of atomic radius
The SI unit for any mass is the kilogram. However, the mass of particles such as neutrons are often expressed either in atomic mass units (amu), or in electron-volts (eV) or some multiple such as MeV - but those, of course, are not SI units.
The SI unit of mass is the kilogram.
