Read the unit first
Precious-metal quotes commonly use troy ounces. One troy ounce is exactly 31.1034768 grams. It is a unit of mass, not a measure of purity.
Keep the conversion consistent
One kilogram contains approximately 32.1507466 troy ounces. To turn a price per troy ounce into a price per gram, divide by 31.1034768.
Try a round-number price
At a hypothetical USD 3,000 per troy ounce, pure gold has a reference metal value of about USD 96.45 per gram. That is a conversion, not a dealer quotation.
Weight is only the first layer
Next come purity, currency conversion and transaction costs. A finished item’s gross weight can include stones or other materials; use the relevant metal weight.
