About Troy Ounces
The troy ounce (ozt or oz t) is the global standard for weighing and pricing precious metals - gold, silver, platinum, and palladium. Equal to 31.1034768 grams (about 10% heavier than the avoirdupois ounce), it originates from the medieval fair at Troyes, France, where a standardised weight system facilitated international trade. All gold spot prices quoted on financial markets (LBMA, COMEX, MCX) are priced per troy ounce. A standard 'Good Delivery' gold bar approved by the London Bullion Market Association weighs approximately 400 troy ounces (12.4 kg).
About Nanograms
A nanogram (ng) is one billionth of a gram (10⁻⁹ g). This is the standard mass unit in analytical chemistry, pharmacology, and toxicology for detecting trace substances. Blood plasma concentrations of hormones, drugs, and environmental contaminants are routinely reported in nanograms per milliliter (ng/mL). A typical therapeutic blood level for many medications is in the range of 10-500 ng/mL. In forensic science, nanogram-level DNA quantities can be amplified by PCR to yield a full genetic profile.
