Unit Conversions

The troy weight system is defined by the following conversion factors between its units and the metric/avoirdupois systems:

• 1 troy ounce (oz t) = 20 pennyweights (dwt) = 480 grains (gr)
• 1 troy ounce (oz t) = 31.103 grams (g)
• 1 pennyweight (dwt) = 24 grains (gr)
• 1 grain (gr, troy) = 0.0648 grams (g)
• 1 pound (lb, avoirdupois) = 14.5833 troy ounces (oz t) = 453.5917 grams (g)
• 1 carat (ct) = 3.086 grains (gr) = 200 milligrams (mg) = 0.0002 kilograms (kg)

Key Definitions

• Troy Weight: A system of mass units primarily used for precious metals like gold and silver.
• Carat (ct): A unit of mass used for measuring gemstones like diamonds.
• Karat (kt): A measure of purity indicating the proportion of gold in an alloy. This is distinct from the carat unit of weight.
