Atomic Mass Unit

What is a atomic mass unit?

One unified atomic mass unit (u) is defined as 1/12 the mass of a carbon-12 atom, about 1.6605E-27 kg.

Origin of the atomic mass unit

Introduced to give atomic and molecular masses convenient numerical values.

Where it is used

Atomic, molecular, and nuclear physics and chemistry.

When and where it was developed

The unified (carbon-12) scale was adopted by IUPAC and IUPAP in 1960-1961.

Slug to Atomic Mass Unit conversion formula

The relationship between slugs and atomic mass unit:

1 slug = 8.788648e+27 u
1 u = 1.137831e-28 slug

To convert slugs to atomic mass unit, multiply the value in slugs by 8.788648e+27. To reverse, multiply atomic mass unit by 1.137831e-28.
