The formula for calculating gold value in karats is (gold rate x purity x weight) / 100. For example, 22C gold is 22/24, which equals 0.916 or 91% pure gold. Gold products are often stamped with the 916 seal to indicate their purity. Here's how the value of gold in a sample can be calculated in carat purity: Value of Gold in the sample: = (Weight of Gold x Purity of Gold x Rate of Gold today) / 24 The purity of gold is generally measured in karats, such as 18k or 24k.
