Units explained
Ounce
The (avoirdupois) ounce (oz) equals one-sixteenth of a pound, about 28.35 grams.
From Latin 'uncia', meaning a twelfth part.
US food portions, postal weights, and boxing weight classes.
Standardized as 1/16 of the international pound from 1959.
Proton Mass
The proton rest mass is about 1.6726E-27 kg.
The mass of the proton, the positively charged nucleon.
Nuclear and particle physics, and chemistry.
Quantified after Rutherford identified the proton around 1917-1920.
