About Scruples
A scruple (s ap) is a unit of the apothecary weight system equal to 20 grains or approximately 1.296 grams. Derived from the Latin 'scrupulus' (a small sharp stone used as a counterweight), it was the basic dispensing unit in pre-metric pharmacy across Europe. The apothecary system divided the fluid ounce into 8 drams, each dram into 3 scruples, and each scruple into 20 grains - a hierarchy memorised by every 19th-century pharmacist.
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).
