What is a ton (assay) (US) used for?

It is a historical mining mass unit primarily used to report precious-metal content on assay certificates and settle ore contracts based on metal amounts.

How does a megagram relate to other mass units?

A megagram (Mg) equals 1,000 kilograms or 1,000,000 grams and is equivalent to a metric tonne (t).

Why does the US assay ton have varying definitions?

Its exact mass has changed depending on historical practice and jurisdiction, which means modern reporting often specifies explicit mass values to avoid ambiguity.
