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 Megatons
A megaton (Mt) equals one million metric tonnes (10⁹ kg). Nuclear weapon yields are measured in megatons of TNT equivalent: the largest weapon ever detonated, the Soviet Tsar Bomba tested in 1961, had a yield of approximately 50 Mt TNT and produced a fireball 8 km in diameter. Annual global CO₂ emissions are reported in gigatons (Gt), but regional emissions data and specific industrial sectors are quoted in megatons. The Chicxulub asteroid impact that caused the Cretaceous-Paleogene mass extinction released energy equivalent to roughly 100 million Mt of TNT.
