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 Although the apothecary system has been replaced by SI units in modern medicine, the apothecary ounce still appears in historical pharmacopeias, traditional herbal medicine texts, and some compounding pharmacy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 Metric Tons
A metric ton (t), also called a tonne, equals exactly 1,000 kilograms. It is the standard large mass unit in the international SI system, used worldwide for shipping, trade, agriculture, industry, and environmental monitoring. Global steel production, grain harvests, CO₂ emissions, shipping freight, and oil production are all reported in millions of metric tonnes. A standard TEU shipping container can carry up to approximately 28 metric tonnes of cargo. Carbon footprint calculators express emissions in CO₂ equivalent tonnes (tCO₂e).
