1. What is Carat Weight?

Carat (ct) is a unit of mass used for measuring gemstones and pearls. One carat equals 200 milligrams (0.2 grams). The carat system provides a standardized way to compare the size of precious stones.

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

• 1 carat = 0.2 grams
• The formula converts grams to carats by dividing the mass by 0.2

Explanation: Since 1 carat is defined as exactly 0.2 grams, converting between grams and carats is a straightforward division or multiplication by this conversion factor.

3. Importance of Carat Measurement

Details: Carat weight is one of the "Four Cs" (along with cut, color, and clarity) that determine a diamond's value. Larger stones are exponentially more rare and valuable.

4. Using the Calculator

Tips: Enter the mass in grams (must be greater than 0). The calculator will instantly convert it to carats. For jewelry applications, results are typically rounded to two decimal places.

5. Frequently Asked Questions (FAQ)

Q1: How many carats are in a gram?
A: There are exactly 5 carats in 1 gram (since 1 ct = 0.2 g).

Q2: What's the difference between carat and karat?
A: Carat (ct) measures gemstone weight, while karat (K or kt) measures gold purity (24K being pure gold).

Q3: How precise should carat measurements be?
A: For commercial purposes, carat weight is typically measured to the nearest hundredth (0.01 ct).

Q4: Does carat weight alone determine a stone's value?
A: No, two stones of equal carat weight can have very different values based on cut, color, and clarity.

Q5: What's considered a "large" diamond?
A: Diamonds over 1 carat are considered substantial, with prices increasing dramatically above this threshold.
