How to Convert Exagram to Sun'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) = 5.028992e-16 Sun'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 Sun's Mass (M☉)
Definition
The solar mass is the mass of the Sun, approximately 1.989 × 10³⁰ kilograms — about 333,000 times the mass of Earth.
Mathematical Relationship
M☉ = 1.98847 × 10³⁰ kg ≈ 333,000 M⊕ ≈ 1,048 M_Jupiter.
Conversion Formula
To convert solar masses to kg: multiply by 1.98847 × 10³⁰.
Practical Applications
Expressing stellar masses: Betelgeuse ≈ 15 M☉, Sirius ≈ 2 M☉, a typical neutron star ≈ 1.4 M☉.
Interesting Facts
The Sun loses about 5 million tonnes per second through nuclear fusion (E=mc²), but that's only 10⁻¹³ M☉ per year.
Common Mistakes
The Sun is losing mass continuously through radiation and solar wind — its mass is not quite constant over billions of years.
Educational Tips
Almost everything in astronomy uses solar masses: stars (0.1–100 M☉), galaxies (10⁹–10¹² M☉), black holes (3–10⁹ M☉).
