## How to Calculate How Much 18 Karat Gold is Worth

In order to calculate how much 18 karat gold is worth, one must know:

1. The weight of the gold bullion
2. The purity of the gold bullion

Weight can be measured in grams but because precious metal prices are quoted in Troy Ounces, it is generally easier to work in these units of mass. 1 Troy Ounce is equal to 31.1034768 grams. Therefore:

#### To convert grams to Troy Ounces, use the formula:

Troy Ounces = Grams / 31.1034768

Purity is measured in Karats or Millesimal Fineness. Karats are a measure of gold purity where 24 karats represents 24 out of 24 parts gold. Thus 18 karat gold is 18/24 which equals .75 or 75% pure gold. Millesimal Fineness is a more accurate measurement of purity which is based on parts out of 1000. Thus 75% gold is a Millesimal Fineness purity of ’750′.

#### Therefore, the formula to calculate how much 18 karat gold is worth is:

(Spot Price of Gold * Weight of Gold (Troy Ounces)) * (75/100)

## 18 Karat Gold Jewelry

18 karat gold is 75% pure gold and maintains much of gold’s original ‘yellowness’ as it is still very much gold. The remaining 25% is made up of other metals, usually copper, silver, nickel or zinc. Such metal mixes are known as alloys.

In most countries including the US, jewelry is seldom made from gold of a higher purity than 18kt as it is too soft and not suitable for the purpose of everyday usage. 18kt gold is therefore one of the highest purities in which jewelry is commonly available and consequently is a very valuable form of gold jewelry.

Generally, all jewelry bought from a reputable seller will be stamped with a ‘hallmark’ indicating the item’s purity. This may be ‘18kt’ as expected or ‘750’ which is a value based on the millesimal fineness scale and indicates 750 parts out of a 1000 i.e. 75%.
