Frequently Asked Questions (FAQ)

1. What is the difference between Karat and Fineness?

Karat measures gold purity out of 24 parts (e.g., 22K is 22 parts gold). Fineness measures purity out of 1000 parts (e.g., 916 means 91.6% pure). Both represent the same thing.


2. Can this tool test the purity of my gold?

No. This is a mathematical calculator. You must already know the purity of your item (usually from a hallmark stamp like '916' or '750'). To find an unknown purity, you need a physical test from a jeweler.
