Units explained
Kilogram
The kilogram (kg) is the SI base unit of mass, defined by fixing the Planck constant h at 6.62607015E-34 J s.
From Greek 'khilioi' (thousand) plus 'gramma' (small weight).
The worldwide base unit of mass in science, commerce, and everyday life.
Adopted in 1795; redefined through the Planck constant on 20 May 2019.
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.
Kilogram to MeV/c2 conversion formula
The relationship between kilograms and mev/c2:
To convert kilograms to mev/c2, multiply the value in kilograms by 5.609589e+29. To reverse, multiply mev/c2 by 1.782662e-30.
