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.
Atomic Mass Unit
One unified atomic mass unit (u) is defined as 1/12 the mass of a carbon-12 atom, about 1.6605E-27 kg.
Introduced to give atomic and molecular masses convenient numerical values.
Atomic, molecular, and nuclear physics and chemistry.
The unified (carbon-12) scale was adopted by IUPAC and IUPAP in 1960-1961.
