How to Convert Carat to Earth's Mass
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) = 3.348850e-29 Earth's Mass (M⊕).

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 Earth's Mass (M⊕)
Definition
The Earth mass is the mass of planet Earth, approximately 5.972 × 10²⁴ kilograms.
Mathematical Relationship
M⊕ = 5.9722 × 10²⁴ kg ≈ 5.972 Yg (yottagrams). Earth = 1 M⊕ by definition.
Conversion Formula
To convert Earth masses to kg: multiply by 5.9722 × 10²⁴.
Practical Applications
Expressing exoplanet masses (e.g., 'a planet of 3 Earth masses'), moon masses, and asteroid masses.
Interesting Facts
Earth gains about 40,000 tonnes of mass per year from cosmic dust — but that's only 10⁻¹⁷ of its total mass.
Common Mistakes
Earth's mass is hard to visualize. The key insight: it's known from G × M⊕ (the gravitational parameter), not M⊕ alone.
Educational Tips
Cavendish 'weighed the Earth' by measuring G. If you know g (9.8 m/s²) and Earth's radius, you can calculate M⊕ = gR²/G.
