**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.

**Short Ton** (abbreviations: **shton, or ton U.S.**): is a non-SI metric unit of mass. Although, it is used principally as a unit of mass, it has acquired a number of meanings and uses over long years. It is equivalent to 907.2 kilograms (Kg), or approximately 2000 pounds (lb), or 0.9072 metric tons, or 0.892913 long tons (imperial).

## How to Convert Atomic Mass Units to Short Tons

*Example: How many Short tons are equivalent to 79.27 atomic mass units?*

As;

1 atomic mass units = 1.8298665171398E-30 Short tons

79.27 atomic mass units = Y Short tons

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

Y equals 79.27 times 1.8298665171398E-30 over 1

(i.e.) Y = 79.27 * 1.8298665171398E-30 / 1 = 1.4505351881367E-28 Short tons

Answer is: 1.4505351881367E-28 Short tons are equivalent to 79.27 atomic mass units.
