1. What is Carat Weight?

A carat is a unit of mass used for measuring gemstones and pearls. One carat equals 200 milligrams (0.2 grams). The carat is divided into 100 points for precise measurements.

2. How Does the Conversion Work?

The calculator uses the simple conversion formula:

Where:

• \( Carats \) — The weight of the gemstone in carats
• \( 0.2 \) — Conversion factor (1 carat = 0.2 grams)

3. Importance of Accurate Measurement

Details: Precise carat measurement is crucial in gemology as it significantly affects a gemstone's value. Even small differences in weight can lead to substantial price variations.

4. Using the Calculator

Tips: Enter the carat weight of your gemstone. The calculator will instantly convert it to grams. Carat values can be entered with up to 4 decimal places for precision.

5. Frequently Asked Questions (FAQ)

Q1: Is carat the same as karat?
A: No, carat (ct) measures gemstone weight, while karat (K or kt) measures gold purity.

Q2: How precise are gemstone scales?
A: Professional gem scales measure to 0.01 or 0.001 carats. Jewelers often use "points" (1 point = 0.01 carats) for small stones.

A: The Cullinan diamond was 3,106 carats (621.2 grams) in rough form.

Q5: Why is carat weight important?
