Dalton conversions

About 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 (Da) is equal to 1.660538921(73) × 10^-27 kilograms (1 Da = 1.660538921(73) × 10^-27 kg).

The Dalton (Da) is also equal to 1,822.88839 electron rest mass (m_e).

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.
