Gold Purity Conversion: From 18K to 24K and Beyond

Gold comes in various purities, typically ranging from 14K for durable diamond jewelry to 24K for investment coins. When melting and alloying, jewelers constantly need to convert weights between these purities. The Jewell Master Purity Conversion Calculator does the heavy lifting for you.

The Science of Conversion

If you have 10 grams of 18K gold, how much 22K gold can you make from it? By multiplying the current weight by the ratio of the current purity to the target purity, this tool gives you exact theoretical yields, minimizing loss and maximizing efficiency in the workshop.
