The weight of gold is measured in troy ounces (1 troy ounce = 31.1034768 grams), however its purity is measured in ‘carats’. ‘Caratage’ is the measurement of purity of gold alloyed with other metals. 24 carat is pure gold with no other metals.
Simply multiply the weight of your jewelry in grams by its purity. For example, if you have an 18K ring that weighs 7 grams, knowing that 18 karats equals 75% purity, you can calculate that the pure gold in the ring is 5.25 grams. One troy ounce is equal to 31.1 grams, while a regular ounce is equal to 28.34 grams.
