What is a ton (assay) (US) [AT (US)] used for?

It is a historical mass unit primarily used in mining and assaying to report precious metal content and to calculate payments based on ore metal concentrations.

Why convert from ton (assay) to proton mass?

Converting to proton mass connects macroscopic mass measurements to fundamental particle scales, which is useful in nuclear physics, astrophysics, and related scientific calculations.

Is the mass of the ton (assay) always the same?

No, the exact mass of the ton (assay) (US) [AT (US)] has varied historically and by jurisdiction, so confirming the used value is important.
