Weight Conversion Chart for Gold, Silver and Gems:

Gold and silver are commonly 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.

To Convert:

• Avordupois Ounces to Troy ounces multiply by .91
• Avordupois Ounces to pennyweight multiply by 18.2
• Avordupois ounces to grams multiply by 28.35
• Troy ounces to grams multiply by 31.1
• Troy ounces to pennyweight multiply by 20
• Troy ounces to pounds troy, divide by 12
• Pennyweight to grams multiply by 1.56
• Pennyweight to troy ounces multiply by .05 (or divide by 20)
• Grams to pennyweight multiply by .64
• Grams to troy ounces multiply by .032
• Grams to carats multiply by 5
• Carats to grams multiply by .2 (or divide by 5)
• Carats to "Points" multiply by 100.
