An atomic mass unit (abbreviated: amu, u, or Da) is a unit of measurement that is used to measure the mass of atoms. The atomic mass unit is equal to the ​112 of the mass of the carbon-12.

The unified atomic mass unit and the dalton are different names for the same thing. The dalton name is used more over time.[1][2][3] The unit is named after John Dalton, an 18th-century naturalist and teacher.
