Newton (abbreviation: N): is the International System of Units (SI) derived unit of force. It is named after Isaac Newton in recognition of his work on classical mechanics, specifically Newton's second law of motion. One newton is the force needed to accelerate one kilogram of mass at the rate of one metre per second squared in direction of the applied force.
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 Newtons to Atomic Mass Units
Example: How many atomic mass units are equivalent to 77.65 newtons?
As;
1 newtons = 6.142770466979E+25 atomic mass units
77.65 newtons = Y atomic mass units
Assuming Y is the answer, and by criss-cross principle;
Y equals 77.65 times 6.142770466979E+25 over 1
(i.e.) Y = 77.65 * 6.142770466979E+25 / 1 = 4.7698612676092E+27 atomic mass units
Answer is: 4.7698612676092E+27 atomic mass units are equivalent to 77.65 newtons.
