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 While rarely used in modern commerce (having been replaced by grams in most applications), the avoirdupois dram still appears in some spice and herbalist contexts, in US gunpowder loading data (where charges are specified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 Stones
A stone (st) equals 14 pounds or approximately 6.350 kg. It is the standard unit for expressing human body weight in the United Kingdom and Ireland, where a person will say they weigh '11 stone 4' (meaning 11 stone and 4 pounds, or 158 lb / 71.7 kg). Despite the UK's official adoption of the metric system, stones remain the dominant unit for personal body weight on British bathroom scales, in doctors' offices, and in everyday conversation. British newspapers and sports reports routinely describe athletes' weights in stones and pounds.
