## How to Convert Kilograms to Carats

To convert a kilogram measurement to a carat measurement, multiply the weight by the conversion ratio.

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 kilograms multiplied by 5,000.

For example, here's how to convert 5 kilograms to carats using the formula above.
5 kg = (5 × 5,000) = 25,000 ct

### How Many Carats Are in a Kilogram?

1 kg = 5,000 ct

## Kilograms

The 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. It is roughly equal to the mass of 1,000 cubic centimeters 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 103. Kilograms can be abbreviated as kg; for example, 1 kilogram can be written as 1 kg.

## Carats

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

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.
