Units explained
Ounce
The (avoirdupois) ounce (oz) equals one-sixteenth of a pound, about 28.35 grams.
From Latin 'uncia', meaning a twelfth part.
US food portions, postal weights, and boxing weight classes.
Standardized as 1/16 of the international pound from 1959.
Nanogram
A nanogram (ng) equals 10^-12 kilogram.
From the SI prefix 'nano-' (from Greek 'nanos', dwarf).
Molecular biology, forensics, and toxicology.
The nano- prefix entered the SI in 1960.
