This converter turns kilograms into carats instantly, using the exact factor 1 kilogram = 5000 carats. Type any number and the result updates as you go — nothing is sent to a server, so the arithmetic happens entirely in your browser.
The SI base unit of mass, redefined in 2019 in terms of the Planck constant. Exactly 200 milligrams — the mass unit for gemstones and pearls.
Because the relationship is a simple proportion, one multiplication does the whole job. The table further down gives pre-computed values for the amounts people look up most often, and the result panel also reports the reverse conversion so you can check the figure both ways.
The formula
kilograms- The amount you are converting, measured in kilograms
5000- The exact number of carats in one kilogram
carats- The converted result
How it works, step by step
- Enter the number of kilograms you want to convert.
- The value is multiplied by 5000, the exact conversion factor.
- The result is displayed in carats, rounded for readability.
- The unrounded value and the reverse conversion appear underneath so you can verify it.
Worked examples
Converting 5 kilograms
Multiply 5 by 5000. That gives 25,000 carats. A quick sanity check: one kilogram is larger than one carat, so the number should get bigger — and it does.
Converting 72 kilograms
72 × 5000 = 360,000 carats. Working backwards, 360,000 ÷ 5000 returns 72 kilograms, which confirms the factor is applied the right way round.

Frequently asked questions
How many carats are in one kilogram?
Exactly 5000. Every conversion on this page is that single number multiplied by your input, so the result carries no rounding error beyond what is shown.
What is the formula to convert kilograms to carats?
Carats = kilograms × 5000. To reverse it, divide instead: kilograms = carats ÷ 5000, which is the same as multiplying by 0.0002.
Is the kilogram bigger than the carat?
Yes. One kilogram equals 5000 carats, so it is the larger unit.
Why does my answer differ slightly from other kg to carats converters?
Most differences come from rounding the factor too early. This tool keeps full double precision through the calculation and only rounds at the final display step, and it also shows the unrounded value so you can see exactly where any difference appears.
