Weight Conversion Chart for Silver, Gold and Gems

Troy Weight - gold and silver are measured in Troy weight, a system that includes pennyweights, ounces and pounds. The
ounces and pounds do not equal the Avordupois or customary U.S. system that other common goods are measured in. For example a troy ounce weighs about 10 percent more than a Avordupois ounce.

• 24 grains = 1 pennyweight = 1.5552 grams
• 1 gram = .64 pennyweight
• 1 pennyweight = 1.56 grams or .05 troy ounce
• 20 pennyweight = 1 troy ounce = 31.1035 grams
• 12 ounces = 1 pound troy = 373.24 grams.
