When you need this conversion
- Exchanging old jewelry for new pieces in a different karat.
- Comparing prices quoted per gram of 22k with prices quoted for 18k or 24k.
- Planning how much of a karat a jeweler needs to remake an item.
Note that remaking jewelry involves melting losses and labor, so a jeweler's exchange rate is usually below this pure-gold equivalent. See methodology.
