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.
MeV/c2
MeV/c^2 expresses mass through mass-energy equivalence, E = mc^2; 1 MeV/c^2 is about 1.783E-30 kg.
Derived from Einstein's mass-energy relation, convenient for particle masses.
Particle physics, where masses are stated in MeV/c^2 or GeV/c^2.
Came into use with relativistic particle physics in the 20th century.
Exagram to MeV/c2 conversion formula
The relationship between exagrams and mev/c2:
To convert exagrams to mev/c2, multiply the value in exagrams by 5.609589e+44. To reverse, multiply mev/c2 by 1.782662e-45.
How to use this converter
Type a value into the calculator. The result in mev/c2 updates as you type. Tap a quick value, copy the result with one click, or use the swap arrow to jump straight to the MeV/c2 to Exagram converter for the reverse direction.
Step-by-step: convert exagrams to mev/c2
- Write down the value in exagrams (Eg).
- Multiply that value by the factor 5.609589e+44.
- The product is the equivalent value in mev/c2 (MeV/c²).
- To reverse, multiply the mev/c2 value by 1.782662e-45.
Worked examples
Example 1 — Convert 1 Eg to MeV/c²:
