It is defined as one twelfth of the rest mass of an unbound atom of carbon-12 in its nuclear and electronic ground state, and has a value of $1.660538782(83) \\times 10^{-27} kg$. One $Da$ is approximately equal to the mass of one proton or one neutron. The CIPM have categorised it as a \"non-SI unit whose values in SI units must be obtained experimentally\"."^^ ; ; 0.00000000000000000000000000166053878283 ; 1.66053878283E-27 ; "http://dbpedia.org/resource/Dalton"^^xsd:anyURI ; , ; ; ; "http://en.wikipedia.org/wiki/Dalton?oldid=495038954"^^xsd:anyURI , "http://en.wikipedia.org/wiki/Atomic_mass_unit"^^xsd:anyURI ; ; "Da" ; "u"^^ ; "D43" ; "atomic-mass-unit" .
