Units explained
Mace
The mace equals one-tenth of a tael, about 3.78 grams.
From the Chinese 'qian'; 'mace' is the European trade name.
Chinese and Southeast Asian gold and traditional-medicine trade.
Part of the traditional Chinese tael system.
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.
