How to Convert Exagram to Proton 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) = 5.978637e+41 Proton Mass (mp).

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 Proton Mass (mp)
Definition
The proton mass is the rest mass of a proton, approximately 1.673 × 10⁻²⁷ kilograms or about 938.3 MeV/c².
Mathematical Relationship
mp ≈ 1,836 × mₑ ≈ 1.00728 u. About 0.1% heavier than a neutron.
Conversion Formula
To convert proton masses to kg: multiply by 1.67262192369 × 10⁻²⁷.
Practical Applications
Nuclear energy calculations, radiation therapy dosimetry, and proton beam therapy for cancer.
Interesting Facts
A proton's mass is mostly from the kinetic energy of quarks and gluons (via E=mc²), not from the quark masses themselves (~1%).
Common Mistakes
Assuming quarks make up most of the proton's mass — quarks contribute only ~1%. The rest is binding energy.
Educational Tips
The proton:electron mass ratio (1,836:1) is a fundamental number in physics. It determines atomic structure.
