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.
Pennyweight
The pennyweight (dwt) equals one-twentieth of a troy ounce, 24 grains (about 1.555 g).
From the mass of a medieval English silver penny; symbol dwt from 'denarius weight'.
Jewelry making and precious-metal scrap valuation in the US.
Derived from the medieval English coinage system.
