Convert kilograms to carats for jewelry, gemstones, and precious metal trading. Accurate calculator with industry standards, real examples, and professional conversion tips.
1 kilogram equals 5000 carat
Formula: ct = kg × 5000.00
The carat, equal to exactly 200 milligrams, is the universal standard for weighing diamonds, gemstones, and precious metals in the jewelry industry. With 1 kilogram equaling precisely 5,000 carats, accurate conversion is essential for gemologists, jewelers, and precious metal traders worldwide. Understanding this conversion prevents costly pricing errors in high-value transactions.
Carat weight directly determines gemstone and precious metal value—a single carat difference can mean thousands of dollars in price variation. The jewelry industry relies on this precise metric: 1 kilogram = 5,000 carats exactly. Miscalculation in conversions can result in significant financial losses for retailers, appraisers, and buyers. Professional accuracy is legally required for certified gemstone transactions and insurance valuations.
Jewelry retailers and gemstone traders use kilogram-to-carat conversions when sourcing rough diamonds and precious stones from international suppliers, managing inventory in different measurement systems, and calculating per-carat pricing for wholesale and retail transactions. Accurate conversion ensures consistent pricing across global markets and maintains profit margins.
Precious metal refineries process gold, silver, and platinum in kilogram quantities but report refined gemstone content in carats. Bullion traders convert between kilograms and carats when dealing with mixed metal-gemstone lots, managing inventory across different trading platforms, and settling international transactions where some markets use carats for precious metal content.

Exactly 5,000 carats equal one kilogram. This is a defined standard in the jewelry industry: 1 carat = 200 milligrams, so 1 kilogram (1,000 grams) = 1,000,000 milligrams ÷ 200 = 5,000 carats. This precise ratio is used globally for gemstone trading, precious metal refining, and jewelry certification. For example, a 0.2 kg diamond weighs 1,000 carats.
Carats provide a traditional, industry-standard measurement that jewelers and gemologists have used for centuries. The carat's small size (200 mg) makes it ideal for expressing gemstone weight with precision—a 1-carat diamond is immediately recognizable worldwide, while saying '200 milligrams' would confuse customers. Additionally, carat pricing per unit is how the industry establishes value. The metric system coexists with carats because historical tradition combined with practical utility; converting to kilograms would eliminate the precision and cultural context that the jewelry industry depends upon.
