تحويل أوقية تروي إلى ستون: المعادن الثمينة والأحجار الكريمة والمجوهرات

One troy ounce equals 0.194286 stones exactly. To convert troy ounces to stones, multiply the troy ounce quantity by 0.194286. For example, 10 troy ounces equals 1.94286 stones (approximately 1.94 stones). Conversely, one stone equals 5.14286 troy ounces. This conversion is rarely used in modern precious metals trading but remains important for authenticating antique jewelry and understanding historical gemstone documentation from Commonwealth nations.

The troy ounce became the international standard for precious metals because it provides better precision for valuable commodities and aligns with historical trading practices established in European precious metals markets centuries ago. The troy system's 31.1035-gram standard offers consistent measurement across all precious metals exchanges worldwide, including the London Bullion Market Association and COMEX futures contracts. Stones, being much larger (6.35 kilograms), are impractical for measuring valuable materials where small weight differences represent significant financial value. A 0.1-stone difference equals approximately 635 grams of gold—worth tens of thousands of dollars.
