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 Short Hundredweights
A short hundredweight (cwt, US cwt) equals exactly 100 pounds or approximately 45.359 kg. Used primarily in the United States for commodity trading, it represents the practical 'hundred-pound' unit for measuring coal, agricultural produce, livestock feed, and industrial materials. Commodity markets for cattle, hogs, and grain in the US price their products per hundredweight ($/cwt or $/100 lb). Steel and non-ferrous metal quotations in North America are commonly expressed in dollars per short hundredweight. The 'short' modifier distinguishes it from the UK long hundredweight (112 lb).
