The pros and cons of cynicism. Experts are divided on whether cynicism is good or bad for you, so of course the real answer isnât simple. First letâs look at the negative side of the ledger:
First weigh it in grams or standard ounces. 1 troy ounce is about 31.1 grams or 1.1 standard ounces, â¦so divide by either of those numbers as appropriate, to get troy ounces. Coin silver is an alloy of 90% pure silver and 10% copper so multiply the final result by 0.90 to get the amount of pure silver. 3 people found this useful.
Therefore the troy ounce is 480 grains (31.10 g), compared with the avoirdupois ounce, which is 437.5 grains (28.35 g). So the troy ounce is about 10% heavier (ratio 192/175) than the avoirdupois ounce, which is used for everyday purposes in the United States. Although troy ounces are still used to weigh gold, silver, and gemstones, troy weight is no longer used in most other applications.
