Generate a custom reference table linking karat to fineness and purity. Add the ranges you need instead of relying on a fixed table.
| Karat | Purity % | Fineness ‰ | Fine-Gold Fraction |
|---|
The table uses the mathematical 24-part karat convention. Actual legal marking standards can vary by jurisdiction, so the generated values are a conversion reference rather than a hallmarking determination.
Karat is intuitive in jewellery markets, while fineness expresses the same gold fraction on a 1,000-parts scale. Using both avoids ambiguity when comparing specifications.
18 divided by 24 equals 0.75, which is 750 parts per thousand.
Yes. Use an increment such as 0.5.
No. It is a mathematical conversion generator.
