The unified atomic mass unit (Also known as amu, symbol: u) 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 neutral atom of carbon-12 in its nuclear and electronic ground state, and has a value of 6.60538921099999856.05389210999999250.5389210999999255.3892109999987953.89210999998613268.9210999999195349.2109999991953372.1099999919533731.0999999046325684±×10− kg. One dalton is approximately equal to the mass of one proton or one neutron; an equivalence of saying 1 g mol−1 . The CIPM have categorized it as a "non-SI unit whose values in SI units must be obtained experimentally".

| - The unified atomic mass unit (Also known as amu, symbol: u) 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 neutral atom of carbon-12 in its nuclear and electronic ground state, and has a value of 6.60538921099999856.05389210999999250.5389210999999255.3892109999987953.89210999998613268.9210999999195349.2109999991953372.1099999919533731.0999999046325684±×10− kg.

- An amu is the mass of a carbon atom divided by 12. An amu is also the mass of a proton or neutron. The atomic mass is measured in amu.
- An atomic mass unit (abbreviated amu) was a unit of mass equal to 1/12 the mass of the most abundant isotope of carbon, carbon-12, which contains six protons, six neutrons, and six electrons. In 2372, B'Elanna Torres ordered 0.57 amus of antiproton radiation be bled from the USS Voyager's warp core to treat Tom Paris, who had experienced hyper-evolution due to a warp 10 flight. (VOY: "Threshold") Torres seems to use amu as a unit of radiation rather than mass, which conflicts with the 21st-century definition.
