Atomic mass unit
From Wikipedia, the free encyclopedia
An atomic mass unit is a unit of measurement that is used to measure the mass of atoms. The atomic mass unit (abbreviated: amu or u) is roughly equal to the mass of 1 proton or 1 neutron.
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.
