Dalton, city (1990 pop. 21,761), seat of Whitfield co., extreme NW Ga., in the Appalachian valley; inc. 1847. It is a highly industrialized city in a farm area. Its large tufted-textile industry was begun in the late 1800s and still remains important; the city is the center of the U.S. carpet industry. In the Civil War, Dalton (Confederate headquarters after the Chattanooga campaign) fell to Gen. Sherman in the Atlanta campaign (1864). The Chickamauga and Chattanooga National Military Park is nearby, as is a state park.dalton[′dȯl·tən] (physics) atomic mass unit Daltongang bank robbers of late 1800s; killed in shootout (1892). [Am.

dalton (D) (Da) [dawl´ton] an arbitrary unit of mass, being ¹⁄₁₂ the mass of the nuclide of carbon-12, equivalent to 1.657 × 10−24 g. Called also atomic mass unit.Dal·ton (dawl'tŏn), John, English chemist, mathematician, and natural philosopher, 1766-1844. See: Dalton law, Dalton-Henry law, daltonian, daltonism.
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). [John Dalton] 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.dal·ton (Da, D) (dawl'tŏn) Term unofficially 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). [John Dalton]dalton a unit of mass: 1 dalton is equal to 1 atomic mass unit. Molecular weight is often expressed in daltons. The unit is named after John Dalton, who developed the atomic theory of matter.AcronymsSeeDADalton
