Units explained
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.
Gigagram
A gigagram (Gg) equals 10^6 kilograms, the same as 1,000 metric tons.
From the SI prefix 'giga-' (from Greek 'gigas', giant).
Bulk commodity, emissions, and freight accounting.
The giga- prefix entered the SI in 1960.
MeV/c2 to Gigagram conversion formula
The relationship between mev/c2 and gigagrams:
To convert mev/c2 to gigagrams, multiply the value in mev/c2 by 1.782662e-36. To reverse, multiply gigagrams by 5.609589e+35.

Step-by-step: convert mev/c2 to gigagrams
- Write down the value in mev/c2 (MeV/c²).
- Multiply that value by the factor 1.782662e-36.
- The product is the equivalent value in gigagrams (Gg).
- To reverse, multiply the gigagram value by 5.609589e+35.
Worked examples
Example 1 — Convert 1 MeV/c² to Gg:
1 × 1.782662e-36 = 1.782662e-36 Gg
Example 2 — Convert 100 MeV/c² to Gg:
100 × 1.782662e-36 = 1.782662e-34 Gg
Real-world example — Wavelengths across the spectrum
Optical and atomic-scale phenomena are routinely cross-converted between sub-micron units. A photon of wavelength 800 mev/c2 can be re-expressed in gigagrams for direct comparison with another instrument's calibration data sheet.
800 MeV/c² × 1.782662e-36 = 1.42613e-33 Gg
Real-world example — Molecular dimensions
The diameter of small molecular structures (around 2 mev/c2) is often converted into related sub-micron units when comparing measurements across different microscopy techniques or imaging modalities.
2 MeV/c² × 1.782662e-36 = 3.565324e-36 Gg
