Gold Calculator
Gold purity plays a very important role in gold price calculation. Without understanding purity, you cannot use a gold calculator correctly. Gold purity is measured in karats, which is written as K. The higher the karat, the purer the gold. 24K gold is the purest form of gold. It contains about 99.9% pure gold. This type of gold is very soft and is usually used for coins and bars, not jewelry. 22K gold contains about 91.6% pure gold and is commonly used for jewelry in India. 18K gold has 75% pure gold, and 14K gold has around 58.5% pure gold.
