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 Although the apothecary system has been replaced by SI units in modern medicine, the apothecary ounce still appears in historical pharmacopeias, traditional herbal medicine texts, and some compounding pharmacy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.
About Tolas
A tola is a traditional South Asian unit of mass equal to the weight of a silver rupee coin - approximately 11.664 grams. It was the standard unit for weighing gold and silver across India, Pakistan, Nepal, and Bangladesh for centuries, and remains actively used in gold jewellery markets throughout the subcontinent. Gold is routinely priced and bought in tolas at jewellers' shops (sarrafas) in India and Pakistan. A 10-tola gold bar (116.64 g) is the most popular retail gold bar size in South Asia and the Middle East.
