What is dalton?

The Dalton (or atomic mass unit) is a unit of mass defined as 1/12 weight of carbon-12 in its nuclear and electronic ground state.

    1 Da = 1 u = 1/12 m(12C)

The dalton is equal to 1.660538921(73) × 10-27 kilograms (1 Da = 1.660538921(73) × 10-27 kg), the base unit of mass in the International System of Units (SI). It is also equal to 1,822.88839 electron rest mass (me).

The energy equivalent of 1 dalton:
1 Da = 1 amu = 931.494061(21) × 106 eV/c2 = 931.494061(21) MeV/c2 = 0.931494061(21) GeV/c2

The dalton is used to indicate the mass on an atomic or molecular scale.
