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.
Decigram
A decigram (dg) equals 0.0001 kilogram, or 0.1 gram.
From the SI prefix 'deci-' (from Latin 'decimus', tenth).
Occasional laboratory and pharmacy use.
Part of the original metric system of 1795.
