Enter the mass value in carats into the input field.
Select 'carat [car, ct]' as the input unit and 'grain [gr]' as the output unit.
Click the convert button to get the equivalent mass in grains.
View the converted value displayed clearly for reference or further use.

Key Features

Converts carat measurements exactly into grains based on a defined conversion rate.
Supports unit conversions useful for jewelers, gemologists, and firearms specialists.
Browser-based and user-friendly for quick and easy calculations.
Uses a precise, standardized conversion formula without guesswork.
Ideal for comparing gemstone weights with traditional small mass units.

Examples

1 carat equals approximately 3.086 grains.
5 carats convert to about 15.432 grains.

Common Use Cases

Weighing and pricing diamonds and other gemstones in the jewelry industry.
Comparing pearl weights using traditional mass units on gemological certificates.
Measuring precise projectile and propellant weights in firearms and ballistics.
Specifying arrow and broadhead weights in archery using grains.
Referencing historical pharmaceutical dosages and apothecary measurements.

Tips & Best Practices

Always verify the conversion context since carat and grain units have different traditional uses.
Use the conversion for approximate comparisons rather than precise industrial measurements.
Confirm unit standards when working across regions due to variations in grain usage.
Consider the impact of rounding when dealing with gemstone valuations.
Leverage this tool for bridging measurements between gemology and ballistics fields.

Limitations

Carats are fixed at exactly 200 milligrams, while grains derive from an older avoirdupois pound standard, causing potential regional differences.
Small rounding differences could affect the valuation and precision needed in jewelry.
Grains are primarily used in traditional settings, so conversions might need explanation for modern applications.
