... By definition the atomic mass of the carbon isotope 12C is exactly 12 atomic mass units (amu). It follows that 1 atomic mass unit = 1/ 12 x mass of one 12C atom. Since one atom has a mass of 1.9926 x 10-26 kg, it follows that 1 amu = 1.9926 x 10-26/ 12 = 1.6605 x 10-27 kg. This value is known as the ...
