A quick list of the carat value versus percentage of gold.

• 8 carat = 33.33%
• 10 carat = 41.67%
• 12 carat = 50%
• 14 carat = 58.33%
• 18 carat = 75%
• 22 carat = 91.67%
• 23 carat = 95.83%
• 24 carat = 100%

Keep this in mind when buying gold bullion or scrap jewelry. I often see sellers listing the full weight of the item and then the carat number which can confuse some novice buyers into over paying for the actual gold content.
