About Apothecary Drams
An apothecary dram (dr ap) equals 3 scruples or 60 grains - approximately 3.888 grams. Part of the traditional apothecary system used by physicians and pharmacists from the Middle Ages through the 19th century, it was the standard unit for prescribing and dispensing medicines. Prescriptions written in the apothecary system used special symbols: the dram symbol (℈) and ounce symbol (℥) appear throughout historical medical records and old pharmacy ledgers. The apothecary dram differs from the fluid dram (a volume unit) and from the avoirdupois dram.
About Grams
The gram (g) is the basic metric unit of mass, equal to one thousandth of a kilogram. It is universally used in cooking, nutrition, postal services, and scientific measurement. Almost all food packaging worldwide shows nutritional information per 100 g. A US nickel coin weighs exactly 5 g, a teaspoon of sugar about 4 g, and a standard paperclip approximately 1 g. In chemistry, the gram is central to molar mass: one mole of carbon-12 atoms weighs exactly 12 g. Postal rates are typically scaled per gram or per 100 g.
