About Apothecary Ounces
An apothecary ounce (oz ap) is identical in mass to the troy ounce - approximately 31.10 grams - and equals 8 apothecary drams or 480 grains. It was the standard ounce used by pharmacists and physicians across Europe and North America from medieval times until the 20th century. Although the apothecary system has been replaced by SI units in modern medicine, the apothecary ounce still appears in historical pharmacopeias, traditional herbal medicine texts, and some compounding pharmacy references.

The standard hundredweight in the United Kingdom and much of its historical trading sphere, it reflects the medieval English stone of 14 lb (8 × 14 = 112). British agricultural commodity prices, wool trade records, and livestock market reports historically used long hundredweights. The UK meat trade still occasionally references hundredweights in wholesale pricing.
