Units explained
Tola
The tola equals 180 troy grains, about 11.6638 grams (three-eighths of a troy ounce).
From Sanskrit 'tula', meaning a balance or weighing.
The primary unit for gold and silver across India, Pakistan, and Nepal.
Fixed at 180 grains under British India in 1833.
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.
