unit:Da

Type
Description

The unified atomic mass unit (symbol: $$\mu$$) or dalton (symbol: Da) is a unit that is used for indicating mass on an atomic or molecular scale. 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".
