About converting Kilograms to Carats
Kilograms (kg) and Carats (ct) are both units of weight & mass, so converting between them is a single multiplication: multiply your Kilograms figure by 5,000. Ten Kilograms comes to 50,000 Carats, and a hundred works out at 500,000 Carats.
Rule of thumb: going from Kilograms to Carats multiplies, so the figure always grows — one Kilogram is already 5,000 Carats. If your answer came out smaller, you have the conversion the wrong way round.
What is a Kilogram?
The kilogram was the last SI unit still defined by a physical object — the International Prototype Kilogram, a platinum-iridium cylinder kept in a vault near Paris since 1889. The problem was that it drifted. Careful comparisons against its official copies showed the masses diverging by tens of micrograms, and because the prototype simply was the kilogram by definition, there was no way to say which side had changed. In 2019 it was redefined in terms of the Planck constant, so any properly equipped lab can now realise a kilogram from physics rather than from an artefact.
What is a Carat?
The metric carat is 0.2 grams exactly, standardised early in the twentieth century to replace a tangle of local carats that differed from one gem market to the next. Its name is traditionally traced to the carob seed, once used as a counterweight for small valuables. The trap is the near-identical karat, which is not a mass at all — it measures gold purity in twenty-fourths, so 18-karat gold is eighteen parts gold to six of other metal. Jewellers also split the carat into 100 points, which is why a "fifty-point" diamond is simply half a carat.
To put both in perspective: a liter of water weighs about a kilogram, while a typical engagement-ring diamond weighs about one carat.

Frequently asked questions
How many Carats are in one Kilogram?
There are 5,000 Carats in one Kilogram.
How do I convert Kilograms to Carats?
Multiply the number of Kilograms by 5,000. For example, 10 Kilograms = 50,000 Carats.
What is 100 Kilograms in Carats?
100 Kilograms is equal to 500,000 Carats.
How do I convert Carats to Kilograms?

Is this Kilograms to Carats conversion exact?
Yes, exactly. Both units are fixed against the same base by definition, and 1 Kilogram = 5,000 Carats is the complete value — nothing is rounded away.
