**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.

**Slug** (abbreviations: **ps2pf, or lb.s2/ft**): is a unit of mass in the weight-based system of measures, especially within the British Imperial measurement system and in the United States customary measures system. Systems of measure either define mass and derive weights or define a base weight and derive a mass unit. It is the mass that is accelerated by 1 ft/s2 when a force of one pound (lbf) is applied on it.

## How to Convert Atomic Mass Units to Slugs

*Example: How many slugs are equivalent to 96.24 atomic mass units?*

As;

1 atomic mass units = 1.137E-28 slugs

96.24 atomic mass units = Y slugs

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

Y equals 96.24 times 1.137E-28 over 1

(i.e.) Y = 96.24 * 1.137E-28 / 1 = 1.0942488E-26 slugs

Answer is: 1.0942488E-26 slugs are equivalent to 96.24 atomic mass units.
