Units explained
Quintal (metric)
The metric quintal (q) equals 100 kilograms.
From Latin 'centenarius' (hundredweight) via Arabic 'qintar'.
Agriculture across India, Europe, and Latin America for grain and produce.
Fixed at 100 kg with the spread of the metric system in the 19th century.
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.
