Units explained
Ton (assay) (US)
The assay ton (US) equals about 29.167 grams, a mining-assay convenience unit.
Devised so an assay sample's metal in milligrams reads as troy ounces per short ton.
Ore assaying and metallurgy.
Adopted in assay laboratories to simplify ore-grade calculation.
Picogram
A picogram (pg) equals 10^-15 kilogram.
From the SI prefix 'pico-' (from Spanish 'pico', a small quantity).
Single-cell biology and ultratrace chemical analysis.
The pico- prefix entered the SI in 1960.
Ton (assay) (US) to Picogram conversion formula
The relationship between tons (assay) (us) and picograms:
To convert tons (assay) (us) to picograms, multiply the value in tons (assay) (us) by 2.916667e+13. To reverse, multiply picograms by 3.428571e-14.
