Units explained
Troy Ounce
The troy ounce (ozt) equals about 31.103 grams, one-twelfth of a troy pound.
From the Troy system of weights associated with Troyes, France.
The global standard for pricing gold, silver, platinum, and palladium.
Established in the medieval Troy system and retained for precious metals.
Nanogram
A nanogram (ng) equals 10^-12 kilogram.
From the SI prefix 'nano-' (from Greek 'nanos', dwarf).
Molecular biology, forensics, and toxicology.
The nano- prefix entered the SI in 1960.
