Weight Conversion
In 1527, Henry VIII made the troy system official for coinage; thereafter silver shillings weighed exactly 0.6 troy ounce. Troy weights continued in common use in pharmacy and monetary affairs into the early twentieth century. However, it was abolished in 1878 to avoid any commercial confusion with the avoirdupois pound (16 ounces = 1 lb.). The troy system is practically obsolete today, but the prices of precious metals are still quoted by the troy ounce.
1 Avoirdupois pound = 14.58 Troy ounces
1 Avoirdupois ounce = .9115 Troy ounce
