1. What is Gold Carat?

Gold carat is a measure of gold purity, where 24 carat represents pure gold. The carat system divides gold purity into 24 parts, with each carat representing 1/24th of the whole.

2. How Does the Calculator Work?

The calculator uses the gold carat formula:

Where:

• \( \text{Mass} \) — Weight of gold in grams
• \( 0.2 \) — Conversion factor (1 carat = 0.2 grams)
• \( \text{Purity Percentage} \) — Gold purity as percentage (e.g., 75% for 18k gold)

Explanation: This formula converts mass to carat weight while accounting for the purity of the gold alloy.

3. Importance of Carat Calculation

Details: Accurate carat calculation is essential for determining the value of gold jewelry, understanding gold purity for investment purposes, and ensuring proper valuation in gold trading.

4. Using the Calculator

Tips: Enter mass in grams and purity percentage (e.g., 75 for 18k gold). All values must be valid (mass > 0, purity between 0-100).

5. Frequently Asked Questions (FAQ)

Q1: What is the difference between carat and karat?
A: Carat is used for gemstones (1 carat = 200mg), while karat is used for gold purity. However, the terms are often used interchangeably.

Q2: What are common gold carat values?
A: Common values include 24k (pure gold), 22k (91.7%), 18k (75%), 14k (58.3%), and 10k (41.7%).

Q3: How does alloy affect gold carat?
A: Lower carat gold contains more alloy metals (like copper or silver), which affects color, durability, and value.

Q4: Is higher carat always better?
A: Not necessarily. Higher carat gold is purer but softer. Lower carat gold is more durable for jewelry but contains less pure gold.

Q5: How accurate is this calculation for valuation?
A: This provides the pure gold content. Actual market value depends on current gold prices, craftsmanship, and market demand.
