How to Convert Exagram to Neutron 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) = 5.970408e+41 Neutron Mass (mn).

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 Neutron Mass (mn)
Definition
The neutron mass is the rest mass of a neutron, approximately 1.675 × 10⁻²⁷ kilograms, slightly heavier than a proton.
Mathematical Relationship
mn = mp + 1.293 MeV/c². About 0.14% heavier than a proton.
Conversion Formula
To convert neutron masses to kg: multiply by 1.67492749804 × 10⁻²⁷.
Practical Applications
Nuclear reactor design, neutron radiography, and neutron activation analysis for material composition.
Interesting Facts
A free neutron decays into a proton, electron, and antineutrino in about 14.7 minutes. Inside a nucleus, it can be stable for billions of years.
Common Mistakes
Assuming neutrons and protons have exactly the same mass — the neutron is 0.14% heavier, which is critical for nuclear stability.
Educational Tips
The mn > mp mass difference allows neutron beta decay (n → p + e⁻ + ν̄ₑ). Without it, atomic nuclei as we know them wouldn't exist.
