About Avoirdupois Drams
An avoirdupois dram (dr av) is 1/16 of an avoirdupois ounce - approximately 1.772 grams. Part of the avoirdupois system that governs everyday trade weights in the UK and US, it was historically used to measure small quantities of goods and spices in commerce. While rarely used in modern commerce (having been replaced by grams in most applications), the avoirdupois dram still appears in some spice and herbalist contexts, in US gunpowder loading data (where charges are specified in grains and drams), and in archaic recipe books.
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).
