How the Gold Karat Calculator Works

The calculator uses a simple formula to determine gold purity and value:

1. Karat to Percentage Conversion$$\text{Gold Purity (\%)} = \frac{\text{Karat}}{24} \times 100$$Gold Purity (%)=24Karat​×100

For example:

• 18K gold → (18 ÷ 24) × 100 = 75% pure gold
• 14K gold → (14 ÷ 24) × 100 = 58.33% pure gold

2. Percentage to Karat Conversion$$\text{Karat} = \frac{\text{Gold Purity (\%)}}{100} \times 24$$Karat=100Gold Purity (%)​×24

For example:

• 75% gold → 75 ÷ 100 × 24 = 18K
• 58.33% gold → 14K

3. Gold Value Calculation$$\text{Gold Value} = \text{Weight} \times \text{Purity (\%)} \times \text{Current Price per Gram}$$Gold Value=Weight×Purity (%)×Current Price per Gram

By entering the weight, karat, and current market price, the calculator instantly provides the gold’s monetary value.

Example Calculations

Example 1 – Karat to Percentage

• Gold: 18K
• Conversion: 18 ÷ 24 × 100 = 75% pure gold

Example 2 – Percentage to Karat

• Gold Purity: 58.33%
• Conversion: 58.33 ÷ 100 × 24 = 14K

Example 3 – Gold Value Calculation

• Weight: 50 grams
• Purity: 18K (75%)
• Current Price: $60 per gram

$$\text{Value} = 50 \times 0.75 \times 60 = \$2250$$Value=50×0.75×60=$2250

Example 4 – Quick Conversion

• 24K gold → 100% purity
• 12K gold → 50% purity
• 9K gold → 37.5% purity

These examples show how the calculator handles various scenarios quickly and accurately.
