What is the atomic mass unit (u)?

It is defined as one twelfth of the mass of a carbon-12 atom and is used to measure atomic and molecular masses.

What does electron mass (rest) represent?

It is the invariant mass of a free electron measured in its own rest frame, representing its intrinsic mass.

Why convert atomic mass units to electron mass?

This conversion helps link atomic scale masses to electron dynamics, quantum mechanics, and spectroscopy calculations.
