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.
Milligram
A milligram (mg) equals one-millionth of a kilogram, or 0.001 gram.
From the SI prefix 'milli-' (from Latin 'mille', thousand).
Standard for medicine dosing, nutrition labels, and fine jewelry.
Part of the original metric system of 1795.
