**Definitions:**

**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.

**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 Ounces to Atomic Mass Units

*Example: How many atomic mass units are equivalent to 35.05 Ounces?*

As;

1 Ounces = 1.708E+25 atomic mass units

35.05 Ounces = Y atomic mass units

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

Y equals 35.05 times 1.708E+25 over 1

(i.e.) Y = 35.05 * 1.708E+25 / 1 = 5.98654E+26 atomic mass units

Answer is: 5.98654E+26 atomic mass units are equivalent to 35.05 Ounces.
