What is an atomic mass unit [u]?

An atomic mass unit is defined as one twelfth the mass of a neutral carbon-12 atom and is used to express relative atomic and molecular masses.

What does proton mass represent?

Proton mass is the rest mass of the proton, a positively charged particle found in atomic nuclei, important in nuclear and particle physics.

Can this conversion be used for macroscopic masses?

No, this conversion is only applicable to atomic and subatomic scales and is not suitable for macroscopic mass measurements.
