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

It is a historical mining mass unit used for assay samples, often to report precious metal content, with varying exact mass based on jurisdiction.

Why convert ton (assay) units to petagrams?

Converting to petagrams allows representation of very large masses such as global carbon stocks or ice-sheet changes using a standardized SI unit.

Can I use this conversion for small-scale measurements?

Due to the very small conversion factor, this conversion is mostly suitable for large datasets or scientific modeling rather than small or precise measurements.
