What Is This Tool?
This converter allows users to translate mass values from carat (used in gemstones and pearls) to the gram, an internationally recognized unit of mass. It supports precise and simple conversions essential for jewelry valuation and scientific applications.
How to Use This Tool?
-
Enter the mass value in carats into the input field.
-
Select the source unit as carat [car, ct].
-
Choose the target unit as gram [g].
-
Click the convert button to view the equivalent mass in grams.
Key Features
-
Precise conversion based on the exact definition: 1 carat equals 0.2 grams.
-
Supports gemstone mass measurements in carats and converts them to grams.
-
Browser-based and easy to use with no installation required.
Examples
-
5 carats is converted to 1 gram (5 × 0.2 = 1).
-
0.5 carats equals 0.1 grams (0.5 × 0.2 = 0.1).
Common Use Cases
-
Determining gemstone weights for pricing and certification purposes.
-
Converting pearl masses on gemological documents to grams.
-
Assessing small sample weights during jewelry manufacturing and quality checks.
Tips & Best Practices
-
Use the tool for small mass conversions within the jewelry and gemological fields.
-
Confirm units before conversion to ensure accurate interpretation.
-
Be aware of rounding effects when dealing with very small fractional carat values.
Limitations
-
Carat units are specialized for gems and pearls and not ideal for larger mass measurements.
-
Precision may reduce slightly with very small fractional conversions due to rounding.
-
Instrument resolution can affect the practical accuracy beyond the exact theoretical conversion.
