Assay ton
\Assay ton\
A weight of 29.166 + grams used in assaying, for convenience.
Since it bears the same relation to the milligram that a ton
of 2000 avoirdupois pounds does to the troy ounce, the weight
in milligrams of precious metal obtained from an assay ton of
ore gives directly the number of ounces to the ton.
