Mass is an intrinsic property of a body. It was traditionally believed to be related to the quantity of matter in a physical body, until the discovery of the atom and particle physics. It was found that different atoms and different elementary particles, theoretically with the same amount of matter, have nonetheless different masses. Mass in modern physics has multiple definitions which are co…

WebThis is the common unit for atomic or molecular mass, and 1 amu is thus 1/12 th the mass of a 12 C atom. Using this definition, and relating it to the standard mass of the kilogram, one sees the obvious, that the amu is a very small number. 1 amu = 1.66054x10-27Kg = 1.66054x10-24 g = 1.66054 yoctograms WebConverting from km to m requires multiplying by 1,000, because there are 1,000 m in one km. Converting m to mm requires multiplying by 1,000, because there are 1,000 mm in one m. It follows from these two facts that converting from km to mm requires multiplying by 1,000*1,000=1,000,000.
