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 Gigatons
A gigaton (Gt) equals one billion metric tonnes (10¹² kg). It is the standard unit for planetary-scale mass measurements and global environmental budgets. Annual human CO₂ emissions are approximately 37 Gt CO₂; Earth's atmosphere contains roughly 5,480 Gt of air; Antarctic ice sheet mass is around 26,500,000 Gt of ice. Climate scientists report ice sheet mass balance changes in gigatons per year - the Greenland ice sheet loses approximately 280 Gt of ice annually due to climate change.
