To compute grams in gold, you need to know the purity and weight of the gold. Purity is often measured in karats (K), with 24K being pure gold. Use this formula: grams of pure gold = (weight in grams) x (% purity/100). For example, for 18K gold (which is 75% pure), if you have 10 grams of gold, it would be 10 x 0.75 = 7.5 grams of pure gold.

  2. How do you calculate the value of grams of gold? To calculate the value, multiply the grams of pure gold by the current gold market price per gram.
