Practical Example
Let’s look at an example of how the calculator works in real life.
Suppose you have:
- Gold Weight: 20 grams
- Market Price per gram: $65
Here’s what happens when you click “Calculate”:
- Purity (18K) = 75%
- Pure Gold Equivalent: 20 × 0.75 = 15 grams
- Value: 15 × $65 = $975.00
✅ The calculator displays:
Pure Gold: 15g
Total Value: $975.00
