In chemistry, an atomic mass unit or AMU is a physical constant equal to one-twelfth of themassof an unboundatomofcarbon-12. It is a unit ofmassused to expressatomic massesandmolecular masses. When the mass is
AMU to KG To convert amu to kg, the Royal Society of Chemistry says one atomic mass unit equals {eq}1.66 \times 10^{-27} \, \text{kg}. {/eq}The said conversion is related to the mole and Avogrado's constant. The National Institute of Standards and Technology (NIST) defines a mol...
This made their atomic mass unit about 0.027% smaller than the chemical one. The symbol for both was amu (atomic mass unit). This was of course very confusing, and in 1961 the International Union of Pure and Applied Chemistry ( IUPAC ) decided to redefine the at ......
