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 Grams

The gram (g) is the basic metric unit of mass, equal to one thousandth of a kilogram. It is universally used in cooking, nutrition, postal services, and scientific measurement. Almost all food packaging worldwide shows nutritional information per 100 g. A US nickel coin weighs exactly 5 g, a teaspoon of sugar about 4 g, and a standard paperclip approximately 1 g. In chemistry, the gram is central to molar mass: one mole of carbon-12 atoms weighs exactly 12 g. Postal rates are typically scaled per gram or per 100 g.
