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.

Ton (long, UK) to Atomic Mass Unit conversion formula

The relationship between tons (long, uk) and atomic mass unit:

1 long tn = 6.118773e+29 u
1 u = 1.634315e-30 long tn

To convert tons (long, uk) to atomic mass unit, multiply the value in tons (long, uk) by 6.118773e+29. To reverse, multiply atomic mass unit by 1.634315e-30.
