Units explained
Microgram
A microgram (ug) equals 10^-9 kilogram, or one-millionth of a gram.
From the SI prefix 'micro-' (from Greek 'mikros', small).
Trace nutrients, potent drug doses, and environmental contaminant levels.
The micro- prefix was incorporated into the SI in 1960.
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.
