**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.

**Ounce** (abbreviation: **oz**): is a unit of mass used in customary (imperial) systems of measurement in British. It is most popular in the retail sale of groceries in the United States, also in many other matters of domestic and international trade between customary measurement driven countries.

## How to Convert Atomic Mass Units to Ounces

*Example: How many Ounces are equivalent to 34.15 atomic mass units?*

As;

1 atomic mass units = 5.855E-26 Ounces

34.15 atomic mass units = Y Ounces

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

Y equals 34.15 times 5.855E-26 over 1

(i.e.) Y = 34.15 * 5.855E-26 / 1 = 1.9994825E-24 Ounces

Answer is: 1.9994825E-24 Ounces are equivalent to 34.15 atomic mass units.
