About Long Hundredweights
A long hundredweight (long cwt) equals 112 pounds or approximately 50.802 kg - equal to 8 stone. 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.
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 While rarely used in modern commerce (having been replaced by grams in most applications), the avoirdupois dram still appears in some spice and herbalist contexts, in US gunpowder loading data (where charges are specified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.
