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.
Momme
The momme (mom) equals 3.75 grams.
A traditional Japanese mass unit (Japanese 'monme').
Pearls, and as the standard weight grade for silk fabric.
Part of the traditional Japanese shakkanho system.
