What does 1 atomic mass unit represent?

One atomic mass unit (u) is defined as one twelfth of the mass of a neutral carbon‑12 atom and is used to measure atomic and molecular masses.

What is a petagram used for?

A petagram (Pg) is an SI-derived unit equal to 10^15 grams, commonly used in geosciences and climate science to express very large masses like global carbon stocks or ice-sheet changes.

Why is the conversion value so small when converting from u to Pg?

Because the atomic mass unit measures extremely tiny masses compared to petagrams, the conversion factor results in very small numerical values.
