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.
Kilonewton (abbreviation: kN): is the International System of Units (SI) derived unit of force where 1 kN = 1000 N. It is named after Isaac Newton in recognition of his work on classical mechanics, specifically Newton's second law of motion.
How to Convert Atomic Mass Units to Kilonewton
Example: How many kilonewton are equivalent to 21.48 atomic mass units?
As;
1 atomic mass units = 1.6279275988257E-29 kilonewton
21.48 atomic mass units = Y kilonewton
Assuming Y is the answer, and by criss-cross principle;
Y equals 21.48 times 1.6279275988257E-29 over 1
(i.e.) Y = 21.48 * 1.6279275988257E-29 / 1 = 3.4967884822776E-28 kilonewton
Answer is: 3.4967884822776E-28 kilonewton are equivalent to 21.48 atomic mass units.
