dal·ton (Da),
(dawl'tŏn),Term used to indicate a unit of mass equal to 1/12 the mass of a carbon-12 atom, 1.0000 in the atomic mass scale; numerically, but not dimensionally, equal to molecular or particle weight (atomic mass units).

Dalton
A unit of mass regarded as identical to u (unified atomic mass unit), which is not accepted as standard nomenclature by the IUPAC or IUPAP, equal in mass to 1/12 the mass of a 12C atom. Mass is typically expressed by biologists as kilodaltons (kDa), a unit that sometimes appears as the label on the x-axis of a mass spectrum.Segen's Medical Dictionary. © 2012 Farlex, Inc.
