What is a carat used for?

A carat is a mass unit primarily used for weighing gemstones and pearls, typically defined as 200 milligrams.

How much mass does one tonne represent?

One tonne equals exactly 1,000 kilograms and is widely used to measure large masses in various industries.

Why convert carats to tonnes?

Converting carats to tonnes helps understand the aggregated mass of many small samples in standard industrial units.

What Is This Tool?

This converter tool allows you to transform mass measurements from carats, used mainly for gemstones and pearls, into tonnes, a large-scale mass unit commonly used in science and industry.

How to Use This Tool?

Enter the value in carats that you want to convert.
Select 'carat [car, ct]' as the input unit and 'tonne [t]' as the output unit.
Click the convert button to get the mass equivalent in tonnes.

Key Features

Converts carat (ct) to tonne (t) using accurate unit definitions.
Supports unit conversion for weights ranging from small gemstones to large aggregate masses.
Browser-based tool requiring no downloads or installations.

Examples

Converting 500 carats results in 0.0001 tonnes.
Converting 1000 carats results in 0.0002 tonnes.

Common Use Cases

Weighing diamonds and pearls for pricing and certification.
Aggregating small gemstone masses to understand total weights in industry units.
Reporting emissions or material consumption by converting small mass quantities to tonnes.

Tips & Best Practices

Use scientific notation when handling very small carat values converted to tonnes.
Aggregate multiple small masses to avoid precision loss in large-scale conversions.
Cross-check unit selections carefully to ensure correct conversions.

Limitations

Values in tonnes might appear very small due to the size difference between carats and tonnes.
Precision reduction can happen if decimal places are insufficient during conversion.
Conversion is mainly practical for aggregated carat masses rather than individual stones.
