What is a Carat?
A carat is a standard unit of measurement used to express the weight of gemstones, especially diamonds. The word “carat” originated from the carob seeds that were historically used to balance scales when weighing gems. One carat is equivalent to 0.2 grams. It’s important to note that carats measure weight, not size.
Fun Fact: The size of a gemstone can vary even if the weight in carats is the same, due to the density and structure of different gems!
How to Convert Carats to Grams

The conversion formula for carats to grams is straightforward. Here’s the formula:
1 Carat = 0.2 Grams
So, if you have the weight of a gemstone in carats, you simply multiply it by 0.2 to get the weight in grams. Here’s the step-by-step process:
- Step 1: Take the number of carats (e.g., 5 carats).
- Step 2: Multiply the carats by 0.2 (5 × 0.2).
- Step 3: The result is the equivalent weight in grams (1 gram).
Example: 5 carats × 0.2 = 1 gram.
This simple calculation makes it easy to switch between the two units.
