Kilogram to Carat Converter
Convert kilograms to carats instantly. Free, bidirectional, and fully in-browser.
1 kilogram equals 5000 carats — enter any kilogram value to convert it to carats instantly. This Kilogram to Carat converter is a client-side tool: it applies a single multiplication (ct = kg × 5000) in your browser, updates the moment you type, and works in both directions — edit either field, or press swap, to convert carats back to kilograms. A reference table lists common kilogram values already converted, and nothing you enter is sent to a server.

Frequently asked questions
How many carats are in a kilogram?
One kilogram is 5000 carats. Multiply the kilogram value by 5000 to convert. For example, 10 kg = 50000 ct.
What is the formula to convert kilograms to carats?
ct = kg × 5000. This tool applies it automatically and shows a worked example: 10 kg = 50000 ct.
Can it convert carats back to kilograms?
Yes. Press the swap button, or type into the carat field, and the tool converts carats to kilograms using the inverse of the same relationship.
Is the conversion accurate?
It uses the standard mass and weight definition (ct = kg × 5000), not a rounded approximation, so results are exact to the number of decimal places you select.
Does this work offline and stay private?
Yes. The converter is a browser-side script with no network calls: your values are never uploaded, and once the page has loaded it keeps working without a connection.
