**Definitions:**

**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 55.45 atomic mass units?*

As;

1 atomic mass units = 1.6279275988257E-29 kilonewton

55.45 atomic mass units = Y kilonewton

Assuming Y is the answer, and by criss-cross principle;

Y equals 55.45 times 1.6279275988257E-29 over 1

(i.e.) Y = 55.45 * 1.6279275988257E-29 / 1 = 9.0268585354886E-28 kilonewton

Answer is: 9.0268585354886E-28 kilonewton are equivalent to 55.45 atomic mass units.
