How to Convert Exagram to Earth's Mass
To convert Eg to kg: multiply by 10¹⁵. To convert Eg to Pg: multiply by 1,000.
1 Eg = 10¹⁸ g = 10¹⁵ kg = 10⁹ tonnes.
For example, 1 Exagram (Eg) = 1.674425e-10 Earth's Mass (M⊕).

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.
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.
