How to Convert Carat to Exagram
To convert carats to grams: multiply by 0.2. To convert grams to carats: multiply by 5.
1 ct = 0.2 g = 200 mg = 0.007055 oz.
For example, 1 Carat (ct) = 2.000000e-19 Exagram (Eg).

About Carat (ct)
Definition
The carat is a unit of mass used for gemstones and pearls, equal to exactly 200 milligrams (0.2 grams).
Mathematical Relationship
1 ct = 0.2 g = 200 mg = 0.007055 oz.
Conversion Formula
To convert carats to grams: multiply by 0.2. To convert grams to carats: multiply by 5.
Practical Applications
Diamond grading and pricing, gemstone trade, pearl classification, and jewelry appraisal.
Interesting Facts
The Hope Diamond weighs 45.52 ct (9.1 g). The Cullinan Diamond, the largest gem-quality rough diamond ever found, was 3,106 ct (621 g).
Common Mistakes
Confusing carat (ct, mass) with karat (K, gold purity). 24K gold is pure gold; a 24-carat diamond weighs 4.8 g.
Educational Tips
Carat = weight of a gem. Karat = purity of gold. They sound the same but measure completely different things.
About Exagram (Eg)
Definition
The exagram equals 10¹⁸ grams or 10¹⁵ kilograms — one trillion tonnes.
Mathematical Relationship
1 Eg = 10¹⁸ g = 10¹⁵ kg = 10⁹ tonnes.
Conversion Formula
To convert Eg to kg: multiply by 10¹⁵. To convert Eg to Pg: multiply by 1,000.
Practical Applications
No everyday applications. Describes masses of small moons or large asteroids.
Interesting Facts
Earth's total mass is about 5.97 × 10⁶ Eg. The entire atmosphere weighs 'only' about 5 Eg.
Common Mistakes
Hardly ever encountered — most contexts use 'times 10^x kg' notation instead of exagrams.
Educational Tips
If you need to express masses between Pg and Earth-masses, the exagram fills that gap: 1 Eg = 10¹⁵ kg.
