Question: how much gold in 20 carat?
Answer: Similarly, 22k gold -- the next common percentage of gold for the 'k' mark -- is 22/24 parts pure gold. This is about 92%. And 20 karat gold lies between these values at 20/24, so 83.33% gold content. Therefore, 20 karat gold is not equivalent to 24 karat gold, and so not 100% pure gold.
