The weight of silver is expressed in the Troy system in which a Troy pound equals 12 Troy ounces. Prices quoted for raw silver refer to Troy ounces. To avoid confusion and misunderstanding, we generally express weight in grams. Here's a conversion chart.
- One avoirdupois ounce = 28.349523125 grams
- One Troy ounce = 31.1034768 grams
If you are calculating the weight of silver in a sterling flatware piece, remember that sterling is only 92.5% silver content. It is difficult to calculate the weight of silver in a knife and some serving pieces because part of the piece may be made of something other than sterling, such as a stainless steel blade.
