How to use it
- Enter karat and price per gram of this karat (optional).
- The result appears straight away and updates as you edit.

How it is calculated
Nisab weight = 85 × 24 ÷ karat. Nisab value = nisab weight × price per gram of that karat.
Example
Inputs: Karat = 21. Result: Nisab weight: 97.14 g; Gold purity: 87.5%.
Limits and caveats
- Uses 20 mithqal = 85 g; some scholars weigh the mithqal slightly differently, which changes the nisab.
- The stamped karat can differ slightly from the actual purity of a piece.
