How to Convert Planck Mass to Exagram
To convert Planck masses to kg: multiply by 2.176434 × 10⁻⁸.
mₚ = √(ℏc/G) ≈ 2.176 × 10⁻⁸ kg ≈ 21.76 µg ≈ 1.31 × 10¹⁹ proton masses.
For example, 1 Planck Mass (mₚ) = 2.176434e-23 Exagram (Eg).

About Planck Mass (mₚ)
Definition
The Planck mass is the fundamental natural unit of mass, approximately 2.176 × 10⁻⁸ kg (about 21.76 micrograms).
Mathematical Relationship
mₚ = √(ℏc/G) ≈ 2.176 × 10⁻⁸ kg ≈ 21.76 µg ≈ 1.31 × 10¹⁹ proton masses.
Conversion Formula
To convert Planck masses to kg: multiply by 2.176434 × 10⁻⁸.
Practical Applications
No direct practical applications — a Planck mass is roughly the mass of a flea egg, but its significance is theoretical.
Interesting Facts
Unusually, the Planck mass is macroscopic (~22 µg) — about the mass of a flea egg, a grain of sand, or a small dust mite.
Common Mistakes
Expecting Planck mass to be extremely small like other Planck units — it's actually macroscopic (~22 µg).
Educational Tips
Other Planck units are absurdly small or large, but the Planck mass is surprisingly human-scale: about 20 micrograms.
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.
