How to Convert Kilograms to Carats

To convert a measurement in kilograms to a measurement in carats, multiply the weight by the following conversion ratio: 5,000 carats/kilogram.

Since one kilogram is equal to 5,000 carats, you can use this simple formula to convert:

carats = kilograms × 5,000

The weight in carats is equal to the weight in kilograms multiplied by 5,000.

For example, here's how to convert 5 kilograms to carats using the formula above.

carats = (5 kg × 5,000) = 25,000 ct

How Many Carats Are in a Kilogram?

There are 5,000 carats in a kilogram, which is why we use this value in the formula above.

1 kg = 5,000 ct

Kilograms and carats are both units used to measure weight. Keep reading to learn more about each unit of measure.

What Is a Kilogram?

One kilogram is equal to 1,000 grams, 2.204623 pounds, or 1/1,000 of a metric ton.

The formal definition of the kilogram changed in 2019. One kilogram was previously equal to the mass of the platinum-iridium bar, known as the International Prototype of the Kilogram, which was stored in Sèvres, France.

The 2019 SI brochure now defines the kilogram using the Planck constant, and it is defined using the meter and second.[1] It is equal to the mass of 1,000 cubic centimeters, or milliliters, of water.

The kilogram, or kilogramme, is the SI base unit for weight and is also a multiple of the gram. In the metric system, "kilo" is the prefix for thousands, or 103. Kilograms can be abbreviated as kg; for example, 1 kilogram can be written as 1 kg.

What Is a Carat?

The carat is a unit of mass/weight equal to 200 milligrams.[2]

A carat is sometimes also referred to as a metric carat. Carats can be abbreviated as ct, and are also sometimes abbreviated as CD. For example, 1 carat can be written as 1 ct or 1 CD.
