Units explained
Exagram
An exagram (Eg) equals 10^15 kilograms, or one quintillion grams.
From the SI prefix 'exa-' (from Greek 'hex', six, denoting the sixth power of 1000).
Confined to planetary- and atmospheric-scale mass discussions; never used in daily measurement.
The exa- prefix was adopted by the General Conference on Weights and Measures (CGPM) in 1975.
Planck Mass
The Planck mass equals about 2.18E-8 kg, formed from the constants h-bar, c, and G.
Introduced by Max Planck in 1899 as part of a system of natural units.
Theoretical physics and quantum-gravity research.
Defined by Planck in 1899 from fundamental constants.
Exagram to Planck Mass conversion formula
Note: this conversion uses a generally accepted modern value. Historical and regional definitions of this unit varied across times and places.
The relationship between exagrams and planck mass:
To convert exagrams to planck mass, multiply the value in exagrams by 4.594089e+22. To reverse, multiply planck mass by 2.17671e-23.

Step-by-step: convert exagrams to planck mass
- Write down the value in exagrams (Eg).
- Multiply that value by the factor 4.594089e+22.
- The product is the equivalent value in planck mass (mP).
- To reverse, multiply the planck mass value by 2.17671e-23.
Worked examples
Example 1 — Convert 1 Eg to mP:
1 × 4.594089e+22 = 4.594089e+22 mP
Example 2 — Convert 100 Eg to mP:
100 × 4.594089e+22 = 4.594089e+24 mP
