Kilogram (abbreviations: kg, or kgm): is a SI (metric) system unit of mass (IPK, also known as "Le Grand K" or "Big K") and equivalent to 1/1000 of one gram. Where, at the temperature of melting ice, one gram is the absolute weight of a volume equal to the hundredth part of a metre cube of pure water.
Atomic Mass Unit (abbreviations: amu, or u): also known as dalton (symbol: Da), is a standard unit of mass that used on an atomic or molecular scale (atomic mass). One unified atomic mass unit is about the mass of one nucleon (either a single proton or neutron) and equivalent to 1 g/mol.
How to Convert Kilograms to Atomic Mass Units
Example: How many atomic mass units are equivalent to 60.53 kilograms?
As;
1 kilograms = 6.024E+26 atomic mass units
60.53 kilograms = Y atomic mass units
Assuming Y is the answer, and by criss-cross principle;
Y equals 60.53 times 6.024E+26 over 1
(i.e.) Y = 60.53 * 6.024E+26 / 1 = 3.6463272E+28 atomic mass units
Answer is: 3.6463272E+28 atomic mass units are equivalent to 60.53 kilograms.
