Formula: lb = oz t × 0.0685715
Troy ounces and pounds represent two distinct weight measurement systems that are often confused despite their different origins. One troy ounce equals approximately 0.068571 pounds, but this relationship differs significantly from the standard avoirdupois pound used in everyday measurements. Understanding this conversion is critical for precious metals traders, jewelers, and pharmaceutical professionals who work with exact weight specifications.
Precious metals trading involves substantial financial value—gold trading errors of just 0.1 troy ounces can represent hundreds of dollars in losses. The troy ounce system, used exclusively for gold, silver, and platinum, differs fundamentally from avoirdupois pounds used in general commerce. Misunderstanding this distinction has caused costly mistakes in jewelry manufacturing, bullion trading, and pharmaceutical compounding where precise measurements directly impact product value and safety.
Bullion dealers and commodity traders work exclusively in troy ounces for gold, silver, and platinum transactions. Converting to pounds is necessary when interfacing with general supply chain systems, shipping manifests, and regulatory documentation. International gold markets quote prices per troy ounce, but customs and logistics often require weight in pounds for tariffs and shipping calculations.
Jewelers and gemologists use troy ounces for weighing precious metals used in jewelry creation, but must convert to pounds for shipping, inventory management, and regulatory compliance. A single piece of jewelry may contain multiple troy ounces of gold or silver, requiring precise conversion for accurate cost accounting and production records.

A troy ounce (31.1035 grams) is approximately 10% heavier than an avoirdupois ounce (28.3495 grams). The troy system uses 12 ounces per pound, while avoirdupois uses 16. Precious metals, pharmaceuticals, and gemstones use troy ounces exclusively. This historical distinction persists because precious metals markets adopted the troy system before modern standardization efforts. One troy ounce converts to 0.068571 pounds, not the 0.0625 pounds you'd get from avoirdupois conversion.
International commodity markets established troy ounces as the standard for precious metals centuries ago, and this convention persists across global exchanges including COMEX, London Bullion Market, and Shanghai Gold Exchange. The troy system's 12-ounce pound aligns historically with precious metals trading practices. Converting to pounds (0.068571 pounds per troy ounce) is necessary for shipping and regulatory compliance, but all pricing, contracts, and market quotes remain in troy ounces. Changing this would disrupt trillions of dollars in existing contracts and financial infrastructure.
