What is the unified atomic mass unit equal to?
The unified atomic mass unit (u) is equal to 1/12 of the mass of a carbon-12 atom. This corresponds to a mass of approximately 1.66 x 10^-27 kg. The unified atomic mass unit is commonly used in chemistry and physics to express atomic and molecular weights on a scale relative to the mass of a carbon-12 atom.

What unit of measure is used to measure atomic weight?
expressed in unified atomic mass unit, amuHowever, for practical purposes in the laboratory the relative atomic mass is used so the unit would be gram. (Relative atomic mass compares the mass of all elements to that of the carbon-12 isotope taken as exactly 12)
Si units used for the masses of atomic particles?
The atomic mass unit (u) or unified atomic mass unit (amu) is the standard unit used to measure the masses of atomic particles such as protons, neutrons, and electrons. 1 atomic mass unit is defined as 1/12th of the mass of a single carbon-12 atom.
What equals on atomic mass unit?
One-twelfth the mass of a carbon-12 atom or 1,660538921(73)×10−27 kg.the mass of an electron
